I wouldn't use the Delvac or the redline as ive tried both in my 997 and experienced notchy shifting. The PTX should be your only choice for the 997. A fresh change of PTX results in improved shifting as most of us have noted.

997.1 C2S in SoCal and PTX is the one to get. Sunset Porsche in Oregon sells the individual quarts for future reference.
