I have to agree with both of the other gentleman above regarding the areas that they commented on. I would also comment on the fact that the SSTs and Mavericks that I shot continue to outpenetrate, because of shaft diameter, just about anything else I have put through a bow. I was able to get fletching clearance and very respectable accuracy out of them and the typical TM hunter style rest though it took quite a bit of tinkering...and patience. The Whisker Biscuit suggestion would be a good one except it does reduce arrow speed which, in my mind, tends to nullify the advantage, to some extent, of the skinny carbons penetration capabilities. I like the idea of a drop away design with these arrows much better.
