Yeah, the Blazer vanes, being a stiffer plastic material work much better with the biscuits and other pass-through rests - regular plastic vanes will warp after a few passes through the biscuit. I want to say that turkey feather vanes work fine with the biscuits, as well.
Instead of another summit stand, you might want to seriously consider getting a Tropy Line Tree Saddle.
Hmm, hope they're not out of business - their website is down:
