I used Red Line 75W90NS at $12.50 a pint (used 3) and it works very well. My parts guy at the Porsche department was going to sell me factory at twice that I think. If you have the cash I agree with JFP use the factory stuff. I've heard many folks say it is the best. I have not had any issues at all with the Red Line and it shifts great. Took about 300 miles to smooth out the shifting.
On your 'Cold starts" what is the temp, I know before I changed mine it was very hard to shift below 50 degrees out...once the car warmed up it was ok though.
