I think a 3.5" pitch would be a noticeable gain over a 3" pitch. I know there are tonnes of other reasons why the 850 out performs the T3's but I'm sure that track has something to do with it. The longer pitch makes for less paddles= equal less weight and it seems to climb on top of the snow with less track speed then the 3" pitch. If I ran across one for a decent price I would definitely try one on my 2015 T3. Just my thoughts
