Turbo Nocks are awesome! We (KANSAN & I) use them, they DEFINITELY make a difference. They claim on the website that they will fly no differently with only three or even two fins left, we have a couple of those (OOPS) and they DO fly right in the group with the rest, alot different than your arrow that has the wrinkled fletching for sure!! If you plan on using them with CX arrows, however, you will have to adjust them before fitting them in, they are just a hair too large for the shafts, we filed them down some and they fit right in. You will also need a drop away, we use the Trophy Taker with awesome success. Planning on cutting arrows this week going to try them out with our muzzys, will be sure to let you know the outcome!!!
