Do turbo nocks shoot through wiscker biscits? How heavy are they ? Are they lighter than nock and 3 inch feather? Do they do anything because they spin?

I picked up some at this past September, but haven't had time to mess with them other than shooting a few. Yes they do pass thru a WB, quite well actually. The rep at the show told me they were designed specifically for the WB and drop aways.
