I heard the 09's got a new foam in the seat. I saw a 09 last night and the seat did feel much springier than my 08 seat. I like my seat style and don't want to spend a whole lot but the upgrade would be nice. My question is, "Do any dealer have info on purchasing the foam only?" I know BRP has sold the plastic bases seperately and the I have seen the foam advertised for older sleds.
