Skid question

[yamanytroturbo]

Hello. Im wondering about swapping from 153 to 146 sidewinder skid.
Whats the main differences in the skids? I will be going with 153 track anyways.

I just did this on @farmerschiferl sled. He picked the skid, I just installed it. He maybe able to tell you the difference.
