I'm 214 lbs at 5'10"
I know it is expensive, but I would recommend a custom Penske 8983 from Traxxion Dynamics as a first choice (unless money doesn't matter, then go Ohlins). Nitron is also a great option but I believe the Penske is a better bargain.
A less expensive option is to buy a proper R1 rear shock and get the Satan's adapter (unsure if he still makes them?) to mate it to your bike. Great deals on ebay can be found on slightly used R1 shocks since most of those riders upgrade to Ohlins, Penske or Nitron. Also might be a good idea, if you go the R1 route, to upgrade the spring for your weight. The stock shock is a 550 lb/in so at 220, if you ride without a passenger or a lot of luggage, you'll want a 650 lb/in. If you often carry a passenger, go with a 700 lb/in spring and set the pre-load low when you're alone, high when you carry the passenger.
