I can't add a whole lot to what these guys have said. You just can't argue a whole lot iwth physics.

I, too, think I would shop else where. You have shot a few bows so have a general idea of what fits your person and your wallet--both serious considerations. Another thing that enters into the picture is just how you feel about your choice. You have to feel that you've gotten the best bang for your buck. Confidence in your equipment is paramount to shooting it well.

You also have to determine for yourself what you intend to use the bow for. If it's mainly for hunting and some occasional 3D shooting then ther just isn't much reason to spend a lot of money on a high priced bow. Instead of $800 on a bow I normally advise guys to buy a $350 or $400 bow and spend a little more on higher end rest, sights and other accessories, and of course better arrows. Especially arrows.

Before you buy see if you can shoot a Martin Bengal with the M-Pro cam.

Good luck.
