Can't say anything about the broadheads but..

My new Switchback XT is sweet and with no tuning so far other than initial setup is shooting my Axis ST 400s into TIGHT-TIGHT groups!

A couple nights ago we had 20 mph winds gusting to 40...I was out shooting off my back deck at my bag target at 20 yards with NO effect of crosswind.

I've been shooting STs for two years now. Last season I made a bad shot on a doe at 30 yards. the arrow entered through the hind quarter (and luckily hit the femoral artery), and made a complete passthrough halfway up her back! I was shooting 100 grain THunderheads.
