I've been in the MAs since I was 13, I am 40 now. In my quest of finding a style that could be practiced into the later years, I looked into WC and was most impressed that WC is one of the few striking arts that I saw (outside of Boxing, MT) that actually could use what it practiced in fighting.
I did Shorin Ryu for many years (among other things), this is no ding on the style but after so much kata, 1 step and individual technique practice moving up and down the Dojo floor, when it came to sparing everyone always came out looking like sloppy kickboxers. I never could get all those blocks to work in sparing, the best I could manage was to cover or parry.
I've been doing WC for a year now and upon sparing my old Karate and Kickboxing (PKA rules) friends the result have been somewhat eye-opening. I am a much better in-fighter (an area I've always sucked at), my reflexes have improved (and they scoff at chi sao :shrug
and instead of covering and countering I'm more prone to arresting my opponent's attacks by angling and trapping.
Also, WC shapes actually come out (of nowhere) while sparing, e.g. I can actually use a tan sao, bong sao, jum, jut, etc.
I'm not saying WC is the be-all-end-all, but it really seems to be coming together for me better than before. I believe many of the attributes of WC exist in other arts, but seldom do they seem to be the focal point to the extent they are in WC. I'm often told that WC isn't about the technique but the attributes. I wish I had started this sooner.
