"141 Rear Skid

The powerclaw alone makes it much better with the shorter track.

I run a 141, live & ride above 9k, I ride 70+ days a year & have had 1 day in the last 2 years that I wished I had a longer sled.

The 141 works well enough than I have no desire whatsoever to go to a longer track.

as for differences, attack is the same, but the float skid is more tuneable to the way you want the sled to handle.

Do a search, the 141 was discussed just recently & it was a pretty decent conversation about it.
