Not sure if you would even be interested in spending the extra coin to change again. Regardless I am curious...did you use any type of transmission flush product prior to changing out the fluid? This can and normally will make a really big difference. Also ensuring that you have the correct quantity of fluid as well due to pressures in the system.

Flushing the a manual transmission is a new one on me. Are there any online resources for doing this? I drained the oil and let it drain until it stopped dripping, then refilled to the oil came out of the fill plug.

Royal Purple never really caught my interest. I have friends that swear by Royal Purple products. When cleaning parts coated with RP lubes, nothing ever seems to get all the lube completely off the parts. Parts feel greasy and slimy even after cleaned with heavy duty cleaners. Maybe the solvents in my assortment aren't the correct stuff for the job. Not being able to get parts 100% clean creeps me out.
