Could it be fate that this came across my desk today? I've been reading about the F7 one-lengths extensively this past week. Very intrigued by the concept.

I'm all in on this one. I've been watching Dechambeau for a couple years now with total intrigue. I would love to test the one length irons

I have previously done a self study on wrote about the Pinhawk Single Length Irons: https://www.thehackersparadise.com/forum/showthread.php?87281-RESEARCH-My-SL(Single-Length)-Iron-set-build-test-progression-log

First Name:  Doug

State:  Michigan

Handicap:  18 ( Was a 7.3 four years ago, recovered from neck/spine issues and getting my groove back)

Current Irons:  Wilson Staff V2 or Scratch Blades ( very rare )

Preference:  Definitely One length


I have always been deadly with a 6 iron, therefore have speculated over my many years, great success with one length clubs.

Finally back to my commitment to practice twice ( I am a scratch handicap on the range lol ) to every time playing.  Planning a few trips to the better courses in Michigan and Arizona in the coming months.  

Thank you for the consideration

Current: callaway Apex CF 16 irons

Preference: F7 one length

Always been a callaway guy. Was a 5 handicap until I blew a disc in my back. Looking at one length to keep my posture consistent on all iron shots. Would be a great test.
