I spent several years in Pony Club, and for some reason, they were a fan of wrapping, polos, shipping bandages standing wraps ect., so I learned a whole lot, and I'm very anal about making sure the wraps are on right. I use to use them a lot for doing flat work, partially because I could put different colors on the two diagonals for critiquing purposes ect., but I personally love SMBs. They are much quicker and easier to put on, they actually do support especially when jumping, and you don't have to wash them very often, and when you do, a quick spray with a hose normally works wonders. Not to mention, I have an Arabian now, and I had a TB mare with pretty slender legs, and the standard polo wraps I could find (all the tack stores I went to only had one size) were all too big, so I ended up with a big bunch at the top, which I really don't like. Get SMBs, and you can find the perfect size to fit your horse. There is a girl at my new barn who wraps her horses legs in polo wraps in his stall, because he gets bed sores, and she pulls the tendon towards her, not away, and its definitely uneven, and she leaves them on all day and all night except when she's riding, and I really hope that either I can get to know her well enough, or someone who does can let her know that she's doing it wrong, and show her how to do it right before he seriously injures himself. It is definitely an art, but once you learn how to do it, you can do it quickly and efficiently, and can mix and match, ect., which is always fun. Good luck, and I hope that the above poster can get you a good video that will help.
