I've been using Legacy boots a lot actually, the legacy with my bell boots for gaming. My mare stops HARD in these. She doesn't like SMBs. Not sure why she doesn't but she never really sat down into her stops with any other boots before, but after a couple tries with those puppies she just slid a new plate into the earth's crust.
Of course I'm not going to go off the hanger and say legacy boots are 100% better in every possible way, but I'd like to know what everyone thinks. I do have a couple sets of SMBs as well, never really paid attention to which one I was using until I learned Selena loved them so much.
So just to be clear we're referring to any make and model of the SMBs too. Opinion/Debate time!
