Could a Summit 800HO 151"track be too much sled for me? I am a seasoned, though not what I consider burly rider, 115 lb female. Like to ride off trail, moderate hill climbing. Been riding mostly MXZX 400LC 136"track. Reason I am considering upgrading is lack of flotation, and lack of power. The other option is the 600HO 144". Main concern is #1, will I have trouble making this sled do what I want because of my weight, and if I settle for the 600 (others think this may be enough for me) will I outgrow it in 2 years and wish I had bought the 800? Price is a factor, but mostly want a sled I will be happy with for years to come.
