| OB,
You may find that if taking much off the back from X10's, you will NEED 120gns to help straighten shafts flight as the back ends become stiff and tends to give a bigger kick out of bow.
Tom has been shooting 410's c/w 32mm cut from back end and 120pts, faster than the 380's (c/w 110 stainless pts with 19mm off back) but poss. not as forgiving, at the moment we are testing which permutation works best for 70mts and no other distance, for I, along with many others believe you can tune the bow/arrow for each individual distance of a FITA.
If you can shoot an X10 shaft without cutting any off the back- its probably going to be the best option, but if the arrow becomes so heavy and slow at the longest distances then I would question whether it is the correct choice of shaft type, as side winds will still affect the arrows course no matter what.
These are just my observations , I make no claims about it being difinitive data. |
