Well I'm thinking about a couple different ideas for a sled this winter. This what I have going on, I'm finishing two 2001 Arctic Cat Sno-Pros for my older brother. I have D&D twin pipes on both sleds with non powervalve 600s in them, I'm making both sleds to be quick not fast. Neither will go over 85 on a radar run. Now for my question, I blew up my ProX so now I'm trying to decide what to ride this winter but I have to be able to beat his sleds also. Here is what I have a 98 XC 600 cloned to look like a 98 XCR 440. This is what I have to put on this sled- Vforce3s, Edge Skid (with Tracks USA extension 136), 1 1/4 136 track, Boss HighRise Seat, IQR bars, plus everything stock for this sled. Or instead of building this sled I can buy a 2002 Polaris XC 600 VES with twin pipes, high comp head, Vforce Reeds, stretched out to 136 also, which way should I go? Oh yes I do switch sleds way too often so whatever I do, I'll probably do somthing else also before winter.
