Fletching vanes

[kjl]

I ve got some zombies on the way from boo for my micro suppressor.
They will be as follows;
16.5"
110 grain inserts
Blazer vanes
Lumenocks
125 grain points, 125 grain ramcats
I m using a JoJan mono fletcher, right offset
My questions are;
How far should the vanes be from end of shaft?
Where should the cock vane be placed? stiffest spine of the shaft?

With the flat plastic nock, the Bolt jig sets them at 1.25" from the nock.

I ve noticed quills, diablos , executioners are all different. How critical is distance?

I have found very little with.25" variation. I have done some with nocks in, and out with no noticeable difference at 50 yards.

Hopefully someone that shoots longer distances will chime in before you make a batch.
