Thanks for all the info guys, that really helps! @Zanshin, I train regularly in a Wado Dojo but our sparing is largely un-guided by our sensei. The most formal guidance i've been given in the months I've been doing it is to remain calm and not to put all my weight on my front foot all the time. I guess this is good because we're not all fighting the same because sensei told us X or Y was the best attack, etc. So when sparing I take what I learn in drills, kata and pair work and try to make it work in a "fight". On top of that we have plenty of black belts from purely Wado backgrounds, Shato backgrounds and people who cross train in Wado + Shato or Judo + Wado who offer (some times conflicting, but otherwise good) advice during sparring. But I may be entering another tournament soon so I'm starting to examine my blocks and stance, which is when I turned to YouTube for references and found people doing it WAY differently to the way I was... When I did my first tourney I used a more boxing-esq stance but after my first round a guy from our club (who's a black belt in Shato, Wado and Judo) advised that I use a block that also covered more of my body (as per a drill like fighting stance) as the most common moves I would encounter would be: front snap kicks to the body, side kicks to the body, jabs to the face and reverse punches to the body... his advice did work for me (I won men's 3rd Kyu and bellow ) ... But I started to re-* that advice after visiting YouTube and seeing this very relaxed, low guard used so often. I've since watched this(Kyokushin): http://www.youtube.com/watch?v=W7cHghqmUEg and I can certainly see a high guard working very well in their style of karate; very few "linear" or straight attacks are used, lots of high round house, crescent and axe kicks and a lot of the punches are a bit "hooky" or at least don't come out as straight as the ones I see in sparing in Wado.
