Hello.
I think i have a problem.
I have trained archery for 10 years, and now my tip joint on my fingers have become very rigid/immobile.its not extreme but they are not so agile that my friends. When i put in my fingers in the holes the mid joint is 1/3 or 1/4 inch above the ball.
I think i cant get high revs because my fingers don't come all the way under the ball when i release.
Does any one else have the same problem? Or someone maybe got a solution on the problem?

If the joints are stiff you can combat that with reverse pitch in the fingers.  Due to many rears as a mechanic  my fingers don't bend at the last joint. I use 1/2 inch reverse in the fingers and get plenty of lift
