A Bowtech Patriot single cam or dually or a Bowtech Extreme VFT should do what you want and then some. My bow shoots a 390 grain arrow at 308 fps 71# of draw weight. Knock off about 25-30 fps for your draw length adjustment and you should be in the 283-288 range. No hand shock at all and after adding Limb Saver Ultras, quiet as a mouse. The Patriot Dually or Extreme VFT will add about 5-6 fps above those numbers. If your a pretty experienced archer, you could always step up to the Bowtech Black Knight and add another 20 fps to that.
