i find 1-2 is easier when shifting low in the rpms like in the 1000's and as far as 2-3 i feel like it doesnt jerk when i shift at 3 grand. when i first started driving the car a lot of shifts were rough, my previous car was a prelude so a big difference there.
My previous car was an automatic Volvo. Bigger difference there.
Actually, I string 1-2 out to about 3k as well and it's not jerky for me.
