you know I've got nothing but time on m series with PC tracks and I've really enjoyed it. Only reason I'm changing is I would like to see the difference with a larger paddle track. The PC does a nice job in our light snow here in Colorado IMO. I have found that it does spin, but at times that is too our advantage here. The PC does a quality job of getting the sled back up on the snow, with a properly set-up skid. I also like the ability of the track in all conditions. Especially with a base underneath that the "fingers' can get down to and grab.
I am excited to see how the larger paddles, almost the in-between size, work at throwing the snow. If the name of the game is throwing more snow, the PC does an excellent job in doing that and I think the spinning is an advantage for our turbo'd sleds which are spinning tracks at tremendous speeds. Also the stiffer design of the larger paddles I think will provide support to prevent the folding that we've seen on PC's in the past. It is all a crap shoot honestly, I do NOT do any large climbs and the stopping of the PC downhill is the worst part of the track for sure.
It turned out being a 500$ difference between the PC and the 3". I'll give the 2.6 a try and then go from there. If it doesn't work how I planned I'll change it again next year and keep going from there! Love the input, thanks guy.
