do a general review on any of these broadheads and honestly you find out that they are all sharp and as long as the person can hit what they are pointing out, what ever it hits is going down or bleeding really bad.......
But if you do alot of reading in archery mags or archery hunting mags, alot of the ppros are using the montec or Shuttle-T.
I have several friends that use both. I think you really dont benefit more from either or. One is fixed bladed and the other is removable....but they all have there little unique differances.....
But thats my opinion.......oh and i would pick the montec probably also....and if you ever have problems changing your sight after switching from field tips to broadheads....go shuttle-T.
but then again........

good luck finding something that works for yah though.....
