I would say go MT90. The synchromesh is kinda thin. good for your cold weather, but when it gets hot it won't cushion as well.

I have just switched it up a bit, and I love it so far.

Now, I run 2qts of MT90, followed by 1.5qts of Shockproof heavy. When cold in the morning, no notchy shifting, no stack issues, no nothing. I can start the car at 40 degrees, let the clutch out, and the car doesn't try and stall anymore. With 100% shockproof and the same conditions above, releasing the clutch pedal would shut the car off if you didn't release it slowly. Shockproof is HEAVY stuff in cold!!!!

I use whatever gear oil I have laying around the shop since mine leaks a little. Sometimes its some ghetto brand 75/90 other times 80/90 maybe some 140w for good measure lol. I think power shifting into third and having bad motor mounts is more to blame for failures.

That and spinning the tires on crappy uneven roads.
