i use nap quick spin quick flech there the green ones, they work good for me the one thing i have found bad about them is i shoot hay bails and after a few pass threws the wrap tends to crack but any arrow looses its fletch after a few pass threws for that matere. at least these are cheap and easy to change. just make shure your water is at a full boil, i tryed to jump the gun once with water that was hot but wasnt boiling yet and screwed up the fletch tubes.

Has anyone shot them through a wisker biscuit?

no i use a fall away, but they should do fine in a whisker bisket. i would use the regulare vanes though and not the quik spins, the quik spins have a little lobe on the back of the vane that might drag threw the wisker bisket and slow the speed of the arrow down.

Never used them but a buddy has.  He liked them but they did not hold up at well as a regular wrap and vanes.  he shot them tru a fall away and the ends of the wraps always started to peel up.
