Ever since reading about shooting cock feather-in, in Jack Howard's Bowhunters Catalog some 30+ years ago I've been shooting that way out of all my bows, whether they be recurve or longbow. Immediately after changing, my arrow flight improved dramatically and I had much less feather wear. Plus, as an added bonus was able to lower nocking point significantly, yet still have perfect flight. One will get a little more wear when using cock feather-in out of non-center cut longbows and especially with too stiff of an arrow.
The only other fletching option I will shoot, and it is my preferred preference, is 60/120 four fletch done with the three fletch setting on your jig by applying two feathers in the cock feather position and two in one of the hen feather positions. The hen feather position depends upon whether one is right or left handed. Turn the knob on your fletching jig counter clockwise form the cock feather position to the hen feather position if you are a right handed shooter. If left handed shooter turn the knob clockwise to hen feather position)In effect, done this way one still has a cock feather-in alignment but with 4 fletch. I learned this from Roger Rothhaar shortly after reading the info from Jack Howard.
