I can understand why people are sceptical of the course, but I can honestly say, I found it very useful, and there were others on the course(trad) who have been wc's for 10yrs plus who learnt things they didnt know.Sounds ridiculous, but one of the most important things I learnt was that I had been holding the Squeegie wrongly(as had others) and if I'd continued ,would probably suffer with joint problems in later life.I quickly adapted and my speed and flexibility increased no end.At the end of the day, if someone shows you the ropes locally then great, but you may just be inheriting their bad habits.
