I just dont know, I know for one thing, i will be gettin a 6 pitch 1.25 inch track, most likely studding it.
But I just dont know if I want a 136 or 144, is there really that BIG of a diff? The hills around here have hug drifts, and I've never seen a short trackmake it up, and only a few 136's, what do you think? is the 144 gonna slow me down hardcore?
btw, i have a 99 SRX, stock (soon to be bigbored)

Try out the 136 ice claw. Looked at a section of one, they look good. Maxdlx

im wondering, how are they for off trail though? and they dont seem that sharp or long to get traction

There are 4 ways a track slows down a snowmobile
1. the energy required to bend it (I think this is the biggy). basicly you bend then staighten parts of the track with each inch you move.
this wasted energy can be combatted by running bigger drives and rear axle wheels, bigger wheels the less the track has to bend to go around it. not affected by a longer track
2. the air pump affect. larger paddles will blow more air. if the track it tight to the tunnel, this affect is amplified by not letting the air escape. a long track will only be marginaly worse, you've got 6% (144/136 = 1.06) more paddles, but they "hiding" behind paddles you'd have anyway.
3. the added weight. you've got 6% (144/136 = 1.06) more weight, not nearly as big a difference as studs, and a very minimal effect on top speed. "a body in motion tend to stay in motion"
4. the friction. a longer track rubs against more hyfax and/or moves more wheels. probably not to big of a thing, can be minimised by running looser (mayby with extroverts), or getting a better skidframe like the ExpertX. the third window closed think may or may not help this. with lots of snow, it'll probably help, but not as much as extroverts and sloppy track tension
In all, I doubt it will slow you down hard core. if you're getting extentions, look at getting a big wheel kit, if your getting a new skid, think about and ExpertX.

do you ride trails a lot or off trail a majority of the time?

go with a 136" x 1.25" if you are on trail more than off. also if you are really going to beat on it get it fully clipped and run extroverts. for the average trail rider it wont rachet, but if you are really giving it hell off trail it will rachet with stock drivers.

I think you can get extension that tip up, so they have the same footprint as a 121 on hardpack, but the added length when it gets deep

i think for trails the 144 is a little much, but is definately quite a bit better off trail. Most people dont ride off trail near as much as they would like to think that they do, so a 136 usually suits better. I would go 136.
