RE: how much speed is really lost from a biscuit
ok heres the verdict. i switched from the biscuit to a trophy taker today and i went from 268 to 282 fps. but i think the quick spin speedhunters that im shooting are the reason for the big jump. i think the biscuit was slowing them down alot more then regular vanes since they have the speed lip on them.

Back when i used to shot one i was seeing a 2-3fps drop with a helical fletch and a 1-2 fps drop with straight fletch.
The speed reduction will be increased if the disc is too tight around the shaft or the biscuit isn't tuned properly- it shouldn't be correcting arrow flight, merely giving the arrow something to sit in and slide on when it's on its way outbound.

RE: how much speed is really lost from a biscuit
Well with your proof now Va. it can be said that the difference could be quit a bit. It's great that we now have available equipment at an affordable price to know what is what.
Does make a lot of sense. Something causing that much contact not making that much of a difference just doesn't. It's grabing every vane on the way out, the krinkled vanes are the proof of heat from friction. I wonder how much heat though, or how much it would take to cause the right vane to burst into flames. That would be cool. A flaming arrow would be very cool to hunt with and you wouldn't even have to light it first.
268-282 is a big jump.
