Snow Drags

[RxThunder]

Looking into some local "backyard" snow drags this winter. Nothing too serious. Just for fun. My question is I have a stock 03 and 05 Rx1. The 03 will be studded soon and both have a 1.25 ripsaw. Any advice on quick and easy adjustments to suspensions or opinions on which sled I should run? Fyi these races have different classes for studded sleds.
