I am running a brass c block , ordered d block , with a square pack. I tried a shorty with the weight and it was totally off . Runs great with the "brick" with the current set up.
You're probably sitting about 50-100 grams heavier than us, but with nearly equal F-R weight bias. The shock packages I mentioned should be pretty close to ideal. We came up with our own by trial and error, but I'd still shoot Smiley a message on the Vision Racing Products thread. They make great stuff, right here in the USA, and he seems very helpful to the racers who have questions.
