Evo...don't know that one.
To be fair - it probably has to be worth a go...next you are grounded for bad weather, spend the money you have just saved on a copy of the tapes ....... and a subscription to AIC's.
When I say the tapes are wrong - there were a couple of duff calls...but nothing that would get you shouted at (well not in a loud voice, anyway)...and even that is preferable to the stuff you may have learned in the USA.
Go on...do it....you'll learn something at least.
