Bill, I'm heavy (260 something) and the 350lb spring was rough. When Caryn rode with me it was better but still a stiff ride in back. The 300 is a much better ride. Try the 300lb spring. If it's too soft for your taste we can meet up and I'll give you my 350. It's red.
Thanks, the set that I purchased also has a 350lb spring on the rear, but in researching these shocks at least I know now how relatively easy, and inexpensive, it will be if I want to change it down the road. I still also have the additional option of replacing the rear tire with the better riding Yokohama.
