thanks! you did krav before?! cool beans!! i had no idea! or maybe you posted somewhere and i missed it. i have ALOT of peripheral issues with hands, and feet. those are my biggest problems. so in class i'm not the average bear. i have to work twice as hard to get balanced..if you can call it that with these wobbly knees of mine. and my hands are so gnarled up i have to work around alot of stuff. but i love it.
