Another brand worth considering is Bi-Delta. I'm using the 2.5" Sharkstooth for all my arrows and have been very impressed. They weigh less than 2" Blazers, are .5" tall (like Blazers) and have a very small cross-section so they don't catch much wind (benefit is less wind drift) and perform as well or better (accuracy and grouping) than Blazer or Fusion vanes in my testing. When installed with helical pitch they act like 2 sets of small vanes, with the front set offset from the back set a small amount. They're also quite tough and stick on well - I've yet to have one come off even on pass-through shots on targets and hay bales.
