Stovie, I think the guy in your animation needs to replace the centre of his boss!
Over the years I've shot full twiddly bits recurve, compound, HT and primitive bows competitively and used aluminium, carbon, wood and composite arows. Ive tried three fletchings and four fletchings as well as straight an helical.
At the end of the day, I still shot crap.
ALL arrows will spin in flight, though those using a release aid will spin more slowly than those loosing with fingers. The idea of helical fletching is to increase the spin rate and add to gyrostability, though you can go too far and end up with mini fluflus!
(also wrappingthem the wrong direction around the shaft has the effect of extr drag and loss of stability).
In my personal experience I found no advantage to spiral fletchings, just makes it harder to glue them back on in the field without a jig. I used fletchings like the curlivanes, but the name escapes me at the mo, when shooting carbons and they worked much better at speeding up rotation than spiral vanes or feathers. With feathers I just stick to straight, they tend to have their own bias (being wing feathers) that helps to sin a little more than plastics.
Make up 1/2 doz of each and have a play, see if you can get any difference on the practice butts. To be honest, unless you are seriously good I doubt you will notice any difference with traditional bows.
just my 2p worth
