RE: opinions of the whisker biscuit?
I have only shot a handful of shots through the whisker bisquit, but I have shot about 500 through the whisper disk and I will say that these rests are great. If it was me choosing I think I would lean towards the whisper disc, but I have not had the pleasure of shooting the newly designed whisker bisquit so i can't comment. I think people get discouraged with these types of rests because of fletching contact, but you have to remember the trade off of a full containment rest wich includes added safty and peace of mind of your arrow always being at the ready.
I personally don't know if I will switch to one full time, but I also don't see a better rest for children or someone looking for no moving parts and wanting to forget about their arrow till it is time to shoot. Just My Two Cents
