I've shot some of the bows mentioned and they are all fine bows. Especially the Pearson line with VIBX. I shot for them for the last 4 years.

Changed this year and have to "POP" this one in-----your word---POP. 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. On paper it gives up only 5fps to the SlayR. This might be my hunting bow for sure.

What gets me is that the Nitrous cam draws very smoothly for such a fast bow. Not much valley when you hit the wall, but there is a wall. A real wall. Best thing is to try some and compare them side by side.
