FMJ's are great if you can push them but at your poundage/draw I'd be looking at the Victory VAP arrows. All the good of an Axis but skinnier and stronger. I like them with the Easton Deep Six inserts not the Victory in/outsert.
I hear you but I shoot the 340 FMJ's 73# 30" draw 300fps+\- and I have no spine issues at all. They are field tip accurate to 80yds. The only other arrow I would even entertain shooting is the VAP.
