RE: do you re-use...
To be honest......it kinda (not that I'm really "cheap") became a $$ thing. I bought 3 packs of Rage 3 blades.....and yes....I reused a few heads AFTER sharpening the blades and testing the mechanics.
If I only shot 2-3 times a year....it would be a moot point (and...if replacement blades had been available).
Also....if the (I don't re-use) crowd would accept the premise tht the "I re-use" crowd would NEVER put a head on the end of their arrow that they weren't 100% confident in......we wouldn't need to have this conversation.
Let's put it this way.......
I'm MORE confident in the Rage 2-blade heads I DID re-use.....than I would be with most people's brand new, out of the box head.
So.....this is all relative.
