stock is going to be good for about anything. hard core racers are about the only ones i've seen be able to use diff. dampner. do note the only reason i have the scotts is because it came off my 929 i had for only 3 months.
I just ordered a Hyper Pro RSC in black.. it will be here on Monday. so i will put it on tuesday along with some other stuff that i had ordered... my friend has one his R1 and i love the feel with the damper there.
I went with an Ohlins damper. You can modify the stock damper by swapping out the fluid. Stock fluid is 2.5w according to Stalemate. He's modified 4 of them for racing because he's a cheap bitch. I've modified 2 for different racers and it really helped both of them.
