I still shoot vanes on the standard XX75 aluminum arrows. I posted on this topic once before about the curiosities of feathers and what I would gain from trying an XX78 Super Slam with feathers. I recall Arthur P replying and saying that I wouldn't gain much if anything, due to my heavy old PSE bow with the 2315 aluminum arrows. It's setup to shoot XX75 2315's and is perfectly accurate, so I don't mess with it. "If it ain't broke - don't fix it..."
