New to bowhunting and want to start building my own arrows just to be involved more with the whole skill. 1: is it worth it? 2: how do you pick a: brand, spine, and vanes? 3: all I know is off of nock on and I've heard him talk about offset of the vanes, what's this mean and how do I accomplish this? For what it's worth I shoot a Bear legion 27' draw 52# My current arrows are Easton aftermath 340 spine just based off of archery shop recommendation.
