I'm shooting a Martin Slayr, nitrous cam, 27.5", 55lbs and hunting setup is getting about 280fps. 3D is 293+. By far the fastest bow I've ever had and just as shootable as the best I had from Pearson, such as the 38" Special. Just 25-30fps faster.
Now, if money gets to be an issue you can get the Martin Cougar III with nitrous cams for about $150 less money.
