OK....like I've confessed it's been a little while since I've done any of this stuff. Can't remember which wing I should chose for making arrows. I shoot right handed. Read SOMEWHERE which one to use-can't remember where and which one it stated. I do remember it saying one direction would cause the point to loosen and the other direction the point to tighten.
While looking for arrows (for when I finally get my bow) I've found several sites that specify left wing only on their shafts, which confuses me even more. Doesn't it matter which direction the arrow rotates?

Thanks in advance for your help.

Hasn't mattered with my setups.

I think the only issue with L or R wing feathers is to match them to L or R helical fletching.  As in L helical needs L wing feathers and vice versa.

My rule of thumb has always been Left handed needs RW, Right handed needs LW.  If you already have a clamp get what matches it.
