They both are about dead even as far as speed goes. I think I would give the x force the edge as far as quietness but both are very close. The 08 82nd comes with better strings and cables than the 08x force, but for 09pse changes lots of things. They went with a suppressor, new cam, better strings and cables so it would be a tough call which one I would want. I would shoot both and see which one fits you better. I chose the 82nd over the x force but both bows are slightly different for 09 so shoot them and see which one you like better.
