1.25" IR or 1.5" IR track?

I'm ordering a '24 129" 850 and can't decide between the 1.25" IR and the 1.5" IR track.

Will the sled push with the 1.5" IR and if so, is it worth it for the acceleration the 1.5" provides? I don't care about top end mph and l don't drive like a cross country racer. Thanks!

I was/am leaning towards the 1.5. Is there any issues with that track pushing? I was told by my dealer that he's had customers take off their 1.5's and put on 1.25's because their sleds would push. Thanks for the replies, l greatly appreciate it!

I ride a 2023 Blizzard 850 and have the 1.25IR. It works well most of the time, but because of the extra power, I think the 1.5IR would be better for this engine. If the 1.5 had been offered for the Blizzard last year, I would have chosen it instead.

1.5 IR for sure. That's what I've got in my 129 850 and it's an absolute animal, nothing else I'd rather have for my riding style. I do have better front skis, and the sled performs - IMO - exceptionally well. A track only pushes if the skis don't balance it, but with the shorter track length you won't have much issue.
