I'm right handed
And I fletch my own shafts. I prefer aright helical and depends on the vane itself as to how much helical I'll put on it. Quik spins don't get as much as a duravane but Blazer will get the same as Quik spin. I also locate the vane at the rear of the fletching tool close to the nock as possible. I think this gives a better control on flight and a forward balance point.
