Default 137 X 1.6 Cobra?

For those that installed a 137 x 15 x 1.6 Cobra track would you do it again?
I'm not interested in studs but thinking going a deeper lug track on the 8000RR.
The 2602-909 is a 2 ply. Do they make a single ply silent track?

To be honest id go to the back country 1.75. I had the 1.75 and the 1.6 and the 1.75 was far superior on and off trail. I just bought a new sled and the first thing I'm doing is putting the 1.75 on it.

Put one on my 137". would absolutely do again. So much better of an all around track than the rip 2.

my brother has the 1.6 141 fully studded on his 800, i think it is far superior to my 137 1.25 rip 2 fully studded. Not sure if I can run a 1.75 with studs if I could that's the way I'm going if not the 1.6 cobra with studs is what I'm doing this summer. On or off the trail that 1.6 takes him just about anywhere.

I switched from the Rip 2 w/96 studs, to the 1.6 cobra w/96 studs... Much better in my opinion for on and off trail.

I switched the factory 1.25x137 Rip2 out for the cobra. I don't know if it was worth the money.

I'm surprised you say that. Maybe the combination of having studs and the 1.6 is where you feel the difference. Most will say switch to 1.75, studs are important to me for safety, I hit too many ice patches.

If your not running studs and you run deep snow from time to time, the 1.75 back country would probably be better. I researched this last year and that track has rave reviews.

1.6". The cobra was AWESOME before camoplast came out with the Ice cobra. They changed the track profile at that time so the Ice cobra and the regular cobra are the same minus the studs. The lugs are now thicker and stiffer than the original cobra tracks. I don't think the new profile holds a candle to the old style as far as traction and being able to kick it sideways like the old one. It's weird it has more side bite but less straightline traction. Maybe I'm just biased and am imagining it based upon appearance. The Rip 2 I took off looked too damn similar to the Cobra I was putting on to make me feel like it was a good investment of my funds.

I have an old 141x1.6" Cobra track and I had an extra set of 3.0" shaft with drivers that I should have installed instead. Was going to just put oversized wheels on the rear to take up some of the slack. Maybe I'll get bored this fall and still try it.
