Both are great. Can't really go wrong with either. When I did my research I favored the VAPs over Injections. I forget why. I think the injections didn't have a strong enough spine for me....or I was right at the limit. Where VAPs did.
Also factor in your inserts. I wasn't 100% sold on VAP outcerts. More weight up front than i needed and too many issues with the early designs/materials. They may have addressed it by now. So I used the Deep6 inserts in my VAPs. So far I've been very happy with them (other than the cost). The down side of Deep6 is having to get new broadheads because they have different threads. Kind of annoying considering how many I already have in standard threads. The Rage Hyperbolics in Deep6 have killed everything I've shot at. Accurate, all pass throughs. Oh, another annoying thing about Deep6 is they don't have Judo heads for them. Not a big factor, but I miss them in the field when it's slow.
