Dave,
It's hard to say if you'll benefit or not, but there's only one way to find out... I took the class with only 4 or 500 dives and had a much easier time than one of the more experienced advanced trimix divers that took the course. Why? I already had cave experience and was very comfortable with buoyancy, trim, the various finning techniques, and OOG drills. Number of dives is a poor indicator - you need to look at the quality of your dives. Keep in mind, that even if your skills are top notch, some of the instructors (yes, you Mike
) are still going to knock you down.
Enjoy the class.
