I'm about to do my first arrow build but from what i've heard, distance from the nock for the vanes is preferential as long as there isnt any/a lot of facial contact with the vanes. I suppose it all depends on draw length, anchor point etc. again, thats just from what i've read and seen thus far.

So the helical and offset will be based off of what your bow does with your arrow. Make a mark on a BARE shaft and stand about 3 feet away from a target. Shoot about 5 times and track which way your arrow is spinning. If it spins left, then you need a left helical with a left offset, if it comes out right, you need a right helical with a right offset. Once you figure that out, as far as heat vanes go, give it an inch or so from the base of the nock and you should be fine unless you have a beard then slide it up to prevent facial pressure.
