if they have to wear what almost looks like a welders mit to protect their hands I cant imagine those brushes being too kind on the rest of the bodys skin.
Initially I was deeply disapointed when no one fell off face first into brushes, I realised that this would create a 12 hour shifts supply of youtube "Brush boarding fail" viewing happiness joy for all at a later date.
English guys love inventing this sort of stuff - classic case in point - dendrix/carpet ski/board dry slopes... I love a good snowboarding session but there is no way you can convince me to give that a go...
They have also invented a ski "tread mill" that is like an wide inclined treadmill with a dendrix conveyor - apparently good for coaching as the instructor can stand next to you and fix your technique.
Add to this - a beach towel with a surf board and footprints on it so you can practice your "pop up" in the loungeroom...
