Well, I have had a little free time tonight and since I plan on picking up a new bow here within the next few weeks, I decided to run some numbers through my OnTarget2 software to see what kind of speed and KE I would get from several different set-ups.
Draw Length- 29.5"
Draw Weight- 70lbs
Arrow- 28" Gold Tip Pro Hunter 75/95
Vanes- Bohning Blazers
Nock- Gold Tip GT Nock
Point- 100 grain field tip
Single brass nock and tied in peep sight
Total arrow weight is 398.6 grains
2008 BowTech 82nd Airborne Speed Mods- 330.35 f.p.s & KE of 96.49 ft-lbs
2008 BowTech 101st Airborne Speed Mods- 320.35 f.p.s. & KE of 90.74 ft-lbs
2008 BowTech General Speed Mods- 292.35 f.p.s. & KE of 75.57 ft-lbs
2008 Diamond Marquis- 302.35 f.p.s. & KE of 80.83 ft-lbs
2008 Elite GTO- 322.35 f.p.s. & KE of 91.87 ft-lbs
2008 HCA Iron Mace Trinary- 317.35 f.p.s. & KE of 89.04 ft-lbs
2008 Hoyt Katera- 312.35 f.p.s. & KE of 86.26 ft-lbs
2008 LimbSaver DeadZone DZ-32- 301.70 f.p.s. & KE of 80.48 ft-lbs
2008 Mathews DXT- 304.35 f.p.s. & KE of 81.90 ft-lbs
2008 PSE X-Force7 HF- 313 f.p.s. & KE of 86.81
2008 Ross Cardiac- 302.35 f.p.s. & KE of 80.83
Granted, these numbers aren't true, but they should be pretty close. After playing around with this program for awhile, the 82nd and 101st are really grabbing my attention. Between 320-330 f.p.s. with a hunting rig isn't just impressive, its unheard of!

I don't think you're going to see any discernible difference in a "real life" application within the top 4-5 bows you have listed as far as speed goes. Looks like your going to have your hands full shooting new bows pretty soon.
Good luck budand be sure to post a pic of the one you decide on!
I know, its kinda crazy to think that I use to get pumped about my hunting set-up reaching 280 f.p.s., now it isn't unheard of it goin up another 25-35 f.p.s. I will definetly post pictures when I find "the one". I got a lot of bows to test out!
