Kevin,
I'd tend to agree with Rob, as would many others, Tiffany doesn't shoot an overly high energy set-up, and I've seen their show twice and both times, I thought her penetration looked poor. With something like the ST's penetration shouldn't be as much a factor, and the way ST's fly almost perfectly out of a well tuned bow, it just makes sense to opt for something that is TOUGH, SHARP, and FLIES GREAT, and won't be a detractor for a lower poundage set-up vs. opting for one of the BH's that is best used with a HIGHER poundage/energy set-up. I've know of several people that had issues with the RAGES and not being able to achieve pass-throughs, and opted to switch from them because of that. No pass-through on an animal that may have moved, or on a shot that may have deflected and hit the animal marginally, usually equals a poor blood trail, and a LONG and sometimes disappointing track job!!!! I'll take the pass-through with a 1.125" 4 blade BH over a potential non-pass-through from a 2" 2-blade BH anyday!!!! And actually if you get right down to it, the total cut of a ST is about equal to that of a RAGE!!!!
