RE: bisker wisket
I have one, and I love it. I'm a clutz - so anything that will keep the arrow on for me while I twist myself into a pretzel trying to get a shot - is good by me.
I have had no problems with mine. I did notice Fletchings starting to warble, but it didn't seem to affect my shot. Besides that - I have switched to the Blazers now, and have no problems with that anymore either.
