Wow - no answers? This is one of the best boards. Surprising I didn't find it until now. I like everything he does - the sensual, the rough, the freaky. The guy has a personality, which most porn stars sorely lack. So he makes it interesting, at least for me. It's not just wham, bam, thank you, ma'am. That said, some of my favorite series are as follows.
-Animal Trainer
-POV
-One on One
-Ravishes/Invades/Goes To
