Hi Moose Man. I have a bigfoot with 13" tracks and last fall got totally hung up in loon s**t and out came the winch. ( i shld have left one track on the shoulder or stayed out of it) This spring I took an old bush trail with lots of water ponds in it and the tracks didn't perform well but now i guess I was using to much throttle. I'm going back in a cple of weeks and was just going to go on my 25"s and see how they work as no swamp just water but I am curious when you say swamp do you also mean plain water. I'm from Wpg also and am talking about Beaver Creek area. any other info you have on terrain etc that you travel on and your advice would be helpful as I'm new to this game of make your own trail and really really get stuck by yourself in the boonies. Thx from Mr. Moose
