Yep, the fast ones! The ones with the tall spindles are considerably slower.

The SRX gets my vote too.  OntarioF7’s sled Lake Simcoe February 26, 2021

It was first real muscle sled Polaris built. I believe they came with triple pipes from factory too. It would make a good lake runner in today's world. 

My first throughts went to the Kaw's as well.       .

Trail 54 in HGR territory is now back to being groomed all the way to north portage. Used to be plowed for half of it. Friggin awesome trail! Absolutely minty last night! Enjoy!
