I line mine up, just for consistency's sake and I've heard that it helps. I have no evidence to support the notion that it helps.
Same here... I did that with my old 3 blade Thunderheads and aligned them with the fletchings.
However, here's what I now do:
Magnus Stinger 4 blade - align main blade vertical with bow string. They seem to fly extremely well and don't "plane" as I've heard people talk about.
Slick Tricks 4 blade - no alignment - how can you align a 4 blade head with 3 fletchings???
