I have 3 I am playing with right now out of my Spyder 30 at 70# 29" draw
1) Easton Injexions 330's at 422gr and 12.2% FOC @ 300-301 fps
2) GT Velocity 300's at 427 gr 17.2% FOC @ 297-298 fps
3) Easton FMJ 340's at 455 gr 11% FOC @ 290-291 fps
So far the Injexions seem to have the best overall grouping long range and that is re-tuning for each shaft.
