just looking for a little help in the leg armor category. i have never worn it before but now i have entered a local race and was thinking it would be wise to wear some since i am going to be pushin it. all i am really concerned about is my knees, but am having a hard time finding stuff to try on. so far i have tried 661 race which felt huge, fox launch which seemed like overkill, and fox racing systems which felt the least obtrusive of all of them. what are other people's recommendations in this category. i am almost thinking i would be fine with just kneepads and no shin protection. thanks for your help
