Harley Transmission Oil

Which Schaeffer's oil Products do I use in my Harley Davidson Transmission?

I want to start using Schaeffer oil for my Harley transmission oilHarley.  I am wondering which oil is better to use in the transmission. I read all over the Harley forums that you can use either a gear oil or a straight weight SAE 50W.  What do you recommend I use in the transmission? I have no problem using the #707 SAE 20W-50 in the engine and primary, but what do you recommend for the transmission? Any other information related to this would be greatly appreciated and thank you too for your time.
