While not a 'catch wrestler' I have attended several seminars as well as train under Erik Paulson who uses a lot of catch in his CSW program. Good Stuff.
I LOVE training with catch guys. I would highly recommend getting to train if you can. Some of the neatest grappling little tricks I know I've picked up from catch wrestlers.
A lot of techniques might be considered strongman or dirty tactics by BJJ guys. It's just a different approach. Generally done with a K.I.S.S. mentality, so even I can pick it up. Great art to learn if you can find a teacher or a club
