I wish they were a 1:1 Tommy
I am about 230 these days (trying to get that down) and with my riding style .90 springs would seem to be best.
There's 5W in there now and it dives like a freakin' submarine - I'm doing incremental steps to correct it starting with springs and oil. Over the winter I will work on emulators: I just don't want the down time and all the drilling and such right now.
I'm not a crazy fast rider by any stretch of the imagination (I have no doubt that any number of people here could out-ride me in the twisties) so I'm trying to find the compromise between stiffness and a softer ride.
