JBR... I am running on Progressive 440's 13.5 inch shocks. Soooo much better than standard on any setting! When I ride two up with luggage I am about your weight. I set the progressives on the 3rd ring. When I am solo I just dial it back to say the 2nd ring. The shocks are very easy to adjust though I do recommend you do it without your luggage attached. Happy riding

Setting the shocks a little harder does firm up the ride, but it also increases the dampening so helps prevent bottoming out. Especially when you load up the bike. (the extra weight tends to equalize things on this count). Trust me ... The progressives can be ridden a little firm without being uncomfortable... When I forget to to reset the shocks after riding two up it does get a little bouncy but it is still a better ride than the standard shocks!
