Wife got me a Bitzenburger at xmas. I put together some 4" 4-fletch, left offset.
Compared to the 3-fletch left offset I mostly shoot, the 4-fletch do seem to get spinning pretty fast.
I don't know how important it is for a green archer (I'm one), but more feathers in general help straighten out an arrow that is not in optimum tune. Helical probably even more so, but it may put extra drag on the arrow too. I don't know if it is enough to be a consideration.
I did some bareshaft tuning with different point weight before fletching. The arrows are Gold Tip Warrior 340 shafts at 32". 200gr point. 4-fletch. They do fly well from a 50# Slick Stick. I've probably got close to 60# on my fingers at my 31" draw.
