I shoot the H1 which I am pretty sure is the same as the impacts. Love these arrows best ones I have used so far and tough as nails. APS is the outsert design
I just got my bloodsports this year and so far I'm really loving them. Great penetration into my targets and as stated before very tough. I'm hoping to send one through a buck this year to really test them.
shot the ht1's a couple years ago. very nice arrow. to bad they jacked the prices up on them from when harvest time owned the arrows.
