Hmmmm, never had a problem with that myself. I paper tune as well as step back (pain in the butt) but I did just recently drop my poundage from 72 to 65 and haven't had the opportunity to tune in yet. Hopefully my 350's wont be too stiff. But if so, been looking for an excuse to get some new shafts to play with anyway Only problem with that is I still have 2 or 3 dozen of older CE hunters (pre maxima crap with all that FOC stuff) but I guess I'll have to bite the bullet and give them a try. Been using CE's since they first came out. Been a long standing dedicated user of their products.

The ONLY times I have ever encountered a problem that wasn't a tuning issue or the flight characteristics of a certain fixed broadhead was if that broadhead was really long. Changing the FOC. Since the mass is supposed to be the same, how can a broadhead cause a spine issue as long as it and the field point is the same weight. It's the weight of the tip creating the resistance to the forward motion created by the release of the string which is causing the dynamic flex in the arrow. If the mass= the same of both then from a math standpoint there should be absolutely no difference whatsoever. Only the FOC is differentiated.
