I don't see them working too well. I bet you would have to have your bow pretty well tuned to shoot bare shafts before you did this. I don't see how you would get any sort of consistent offset to them. And I think they would be noisy. Probably not very tough either.
I think I'll pass on this trick. I'm poor, but not that damn poor

.
I honestly can't see this fetish people have with using the least amount of fletching they can? I have shot 21 inch arrows with 5 inch feathers before. I could see if you were shooting long distances like 90 meters or something. However for short known distances I would fletch the crap out of my arrows just for that extra edge. You hear that target archers will purposely paper tune for a nock high/left tear in order to force the fletching to work faster. If so, why would you defeat that by using a small straight fletching with poor steering? Sounds sort of dumb to me to be blunt about it.
