there is a small but pretty dedicated group of mat surfers around the world, just borrow one and get out and try it. Best if you can go with someone already familiar with them, and make sure you have a pair of fins that will give you good drive. You need a good kick and don't try to ride the foam ball. As has been said, if you have a point break available that is best, but don't let a beach break stop you. If you body surf then this will translate well. I like to think of mat surfing as body surfing on steroids, a lot of similarities but there is really nothing quite like it in my experience.
