I understand the reasoning on keeping construction simple and not having an adjustable hosel. But I do see a lot of players really enjoying being able to tinker with shafts from week to week. A shaft can even fit better for certain playing conditions. What if a simple screw and tip receptacle (but non adjustable) was built into a new design. It would greatly help club fitters and the end consumer alike.  It wouldnt effect swingweight as with an after market club connect system. Just a thought but seems as it would be a true benefit without being complex.
