Sumokilt,

My training has been primarily at competative Judo dojos. In traditional sport Judo the need to "try out" street clothes isn't important, but I do see the logic behind it. I just thought I'd play devils advocate and point out an argument that was being missed, but is important to traditionalists. My personal opinion; if one traines diligently, and strives to become as proficient as possible in their chosen art, then what you wear when you need to act will be of little concern.
