I live in Illinoise and sled mosly in the UP or Northern Wisconsin. I take one or two trips a year to the mountains. I currently have a ZR 600 and I am going to upgrade to a F7. The 144 Ext suspension option sounds good on paper but I am concerned that this option may hamper my aggresive rideing style on twisiting norhtern trails. I am looking for feedback on 144 vs the sno pro suspension given this information.
