As a person that is newer to bow hunting than most. I will have to say I somewhat disagree with both accounts on the WASP Jackhammer SST mech. I have shot three times at deer in the field with my bow and all three times with WASP mech. all three deer down within 40 yrds of where they were hit. So until the WASP show me something other than clean quick kills, I will stick with Mech. and WASP's. Not to say that you are not having different results. I am tempted by the G5 Montec, very tempted.
