I just finished some C41 in a Patterson tank. Came out great. I use the JOBO (Tetenal?) C41 Press Kit from B+H.
I put a couple of drops of Photo Flo in the stabilizer. Some say do it, and some say don't. I also use a photo sponge moistened with stabilizer to gently wipe the film as I hang it to dry. The film dries spotless.
Easier than you think. Follow the instructions and temps exactly.
