i have shot alot of of arrows throught my XT (cx,gt,victory,beman,pse,) but so far after about 1000 shots in the past month with my axis i prefer them with my set up.
if you want the straightest arrows go with victory they hold there dozen groups to the tightest tolerances only problem was for me they were hard to get, only plus i saw with the maxima hunters is there "weight forward design" but i didnt see a difference at ranges past 40 yards with my bow compared to nonFOC'd arrows. PSE radial X where as tough as nails, but i like the axis cuz its a great compromise between straight and tough IMO and it does allow for better penetration and the HIT insert did make some difference with my broadheadflight out at 50 yards (i dont shoot past that with fixed blades in practice) and with my tekans past that they flew normal for me
