Speed doesn't mean that this will work. Someone shooting 280 might not be able to accomplish this. Your anchor point matters alot. Also the length of your sight bracket matters. I would say you will be good at 260 but i will not promise you this. However I think 260 is almost too fast for hunting. Thats right, I said it[8D] Need to go heavier for more momentum. I know people don't agree with this but it is my take.
Unless you shoot a Bowtech, then you can still shoot heavier arrows fast.
