Well, if your FOC is still over 11%, I've got nothing to nay say. Do what wrinkles your prune.

I will say though that as long as you fletch those Blazers with about a 5 degree offset or helical, then you shouldn't need to go 4 fletch. According to my testing, they'll shoot fine in a 3-fletch arrangement with both the Snypers and Stingers.
