To be honest, fr3db3ar, hit the nail on the head about the speed issue. Of course everyone is different and wants different thing out of life, thats what makes it interesting. He is also correct about shooting as many as you can and make a list of what you like or dislike about each. It will help out in the final decision. Most any of the new bows are awesome, but the shooter is the deciding factor.
I recently purchased a new bow. It was an Admiral and pushing the limits your looking for, it will compare nicely with anything out there. It is a VERY quiet bow even cranked up to top end, however I am shooting a 29" Easton 340 FMJ at 270 fps, which weighs 470grs, and has a calculated 76# of energy, which should be enough to handle anything in the lower 48 and then some.
I shot most of the newer '09 bows before purchasing it, and several were impressive, but the draw cycle on them pretty much sucked for me. this year there are several that push the envelope hard on the upper 350's, however what you gain in one respect you loose in another. To me the noise was a major factor, and I have not been disappointed at all with my choice. When you can get multiple shots on a pack of hogs before they bust your doing something right.
Of the ones I shot I compared them side by side set at the same draw weights of 65 and then 70 pounds. Some of them I could not draw back at 70 due to the cam designs. Other I could and they weren't what I was looking for.
From the ones I did not choose, here are the top brand contenders,
Mathews, PSE, Diamond, and Bowtech
I wish i could just say go get you "this" bow and you would be happy ever after, but like drawers you are a better judge of what fits you than anyone else.
Good luck
