I recently bought an '07 Bravo to take over for a pretty tired '95 Tundra. I've used the tundra for everything from dragging logs to putting in trails in deep snow and never got stuck in the wide open marshes in deep snow. Recently we've gotten alot of snow so theres maybe 3' of powder in the swamps. I'm finding that I bog down constantly with the bravo. Even getting a full head of steam from a packed trail, I can only make it a ways before the ass end drops on me. Is there that much of a difference between the tundra and the bravo? Or is there something I can do to the bravo to improve the floatation in the deep stuff? The Bravo's front end seems quite a bit lighter than the tundra...and the Bravo has more of a paddle track (maybe 1") versus basically a flat track on the Tundra. Would plastic ski's improve performance? I would appreciate any opinions from those of you who are familiar with these machines.
