Also, the rpm rate of accelleration is much quicker in 1st gear, so the shift comes pretty quick compared to down track when the engine isn't accellerating as quickly making the 2nd gear pull.

I've had the same experience on both counts. I have the shift light set at 5750 & still occasionally hit the rev limiter (set at 6200) on the 1-2 shift if I'm not quick enough. this was on two different brand transbrakes .
