What size 78's are you using? I know they work perfectly fine on a 2413. I'm shooting 2613's but haven't tried them. I'm using 4" for my target arrows and I'll be using feathers for my hunting arras.

Yes feathers are going to be the best for the super slam 78's, this depending on what rest youll be using as well. But either why i always shoot feathers.
