I'll also take a stab at it..

IBO speed is 308.

308 - 10 fps for the ultra nok (aluminum is heavier than a string loop, and makes more noise)

298 fps. - 8 - 10 fps for the kisser and peep.

288 fps. - 5 fps for the whiskers.

283 fps

I, too, will assume xx78's and that you use the uni bushing.

I came up with a 534 grain arrow with 7.4% FOC.

I've generally found that 5 grains = 1 fps.

534 - 350 (ibo) = 184/5 = 37 fps.

283 - 37 = 246 - 250 fps, for a total of approx 70 - 73 ft lbs of KE.

Id estimate the AMO speed of this bow at 230 - 235 fps. Added your 10 lbs of draw weight, I think this is fairly close. I think you'd gain approx 10 fps by loosing the ultranok.
