    Custom Fitting Single Length Irons

    All human beings share the same skeletal, muscle, tendon, and joint functions and from a mechanical standpoint are the same regardless of height or sex. Non-mechanical differences arise in custom fitting however, for instance: the height of a bicycle seat needs to be greater for a taller person than a shorter person even though the mechanical design of the bicycle remains the same. By the same token there is only one true fitting variable in the building of golf clubs and that is club length. Based upon your wrist-to-floor measurement we adjust your club length to correspond to the lie angle of our club-heads in order to ensure a proper fitting.

    Wrist-to-Floor Measurement
    Taking your Wrist-to-Floor Measurement:
    • The wrist-to-floor measurement should be taken while standing on a hard surface.
    • Wear jogging/gym shoes (not golf shoes) not in excess of 1.5" sole.
    • Stand with your back against the wall at strict military attention. Place your shoulders and head against the wall, your feet together, and your arms rigid and straight down at your sides.
    • Hold a pencil in your right hand (right handed golfer). Back your arms against the wall and then take the pencil and make a mark where your left wrist joint hits the wall. Just the opposite for a left-handed golfer.
    • Measure from this mark to the floor.
    • Important: Do not round-up the measurement to the next higher inch increment. For instance, if your measurement is 34 and 7/8″, do not round up to 35″.

    One Iron Golf Club Lengths - Wrist to Floor Measurements

    Very Important:

    Do not order based upon what you consider to be your favorite iron (ie: #7 iron), and do not use that corresponding wrist-to-floor measurement when placing your order. When ordering you need to specify your actual wrist-to-floor measurement to ensure a proper fitting. This chart reflects club length based upon our club-head lie angles. Consequently, our fitting process does not apply to any other brand.

    For the taller golfer:  based upon your wrist-to-floor measurement you may be concerned that your irons would be a typical #3 or #4 iron club length; however, do not compare your measurement to your current #3 or #4 iron. The lie angles of your “long” irons are much flatter than ours which, at your size, requires you to bend over excessively and reach out for the ball at address. The club head lie angle of our irons is 63.5º which is far more upright and allows you, for the first time, to stand upright and much closer to the ball at address resulting in the ideal upright swing posture and swing plane. The taller golfer benefits the most from our fitting formula since they have never played golf clubs that have even come close to fitting them properly. The result being that they have had to develop a very inefficient posture and swing where they are bent over excessively and reaching way out for the ball with every iron in the bag.

    How Does the Wrist-to-Floor Measurement Work?

    It is based upon trigonometry. At the point of ball impact in the downswing, your wrist, the ground, and the club-head, form a right triangle. Assuming an ideal swing posture, there is a non-linear mathematical relationship between your wrist-to-floor measurement while standing at attention and your wrist-to-ground distance at ball impact.

    The club-head lie angles are known for the irons and fairway woods as well as the length of one side of the right triangle based upon your mathematically factored wrist-to-ground distance at impact. This gives us the measurement of two angles and the length of one side. We then use trigonometry to solve for the hypotenuse or club length. This is somewhat oversimplified as we factor in shaft deflection and numerous other factors. The fitting formula that we developed produces the ideal golf club length for anyone regardless of height or arm length.

    Used/Demo Pro-Line Irons

    Jim E. (West Lafayette, US)
    First experiences

    Loved the clubs, very consistent. The distance between clubs was also consistent. Still working on the longer irons, but getting better. I would recommend these clubs.

    Kristin M. (Corning, US)
    Best Irons Ever…

    Flat out the best Irons I have ever played. I hit them as far as my old Taylormade P790 variable length, just much more consistently. I really enjoy the longer, lighter wedges as well which was something I wasn’t sure I would enjoy. I played the regular line last year and switched to the proline this year, definitely a hot rod option, they feel much more performance oriented for a higher swing speed. Original line would be great for average swingers, I swing quick but am iffy on strike, making a performance single length iron the best option. I can also say I tried Cobras at a local shop and one irons feel much better to me.

    Joseph P. (Vancouver, CA)

    Awesome clubs, great fit and already see the difference in consistency!

    Joerg W. (Muskego, US)
    This turned out well

    I was never able to wrap my head around the different shaft lengths in irons so I went with the 1Iron after a friend recommended them to me.
    I ordered the Demo irons to save some money and the clubs arrived in original packaging, well padded.
    No marks, scratches or any other signs of usage could be found.
    My first 18 I played, I broke 60 on the front 9 (55) and I have not yet broken 60 until this past round.
    My shots felt controlled and clean and the same length in all irons definitely has improved my iron game.
    I’m only in my 4th year of playing golf, so I think that’s a pretty good statement.
    I can highly recommend taking the different shot setups for each iron out of
    the equation and go to single length.

    Getting used to single length irons.

    I've only played 27 holes with the new irons (three through SW). My iron play, regardless of whose clubs I'm using, is a lot dependent on the operator, me. So far I'm liking the results with the new irons when I make good swings. The only issue I have is I'm struggling a bit with chipping with these longer-shafted short irons, but I expect I'll figure that out with practice, which I haven't done -- the clubs went straight from the box to the course. I did see there is plenty of info on the web site about using these clubs, so I'll go back there for help. After only 27 holes I'd give a definite thumbs up for making the switch. [Note: When I'm asked for reviews I don't as a matter of personal practice give the very best rating, which should not be construed to mean there is something wrong. However, if I was asked to rate the customer service, it would be five stars.]

    Jerry R. (Madera, US)

    I will get back to you, I haven't used them yet, hopefully by next week?

    Dean H. (Clayton, US)
    Great customer service

    I was accidentally sent the wrong clubs. With one email, my new clubs were sent and arrived in two days.

    Kevin R. (Perth, AU)
