That's fine...more info is always good, and there is certainly more now than there was 2mo ago...but you still didn't answer the question, because nobody can. Call me a smart aleck if you like, but if the OP asks for impossible things, I will point out the reality. If they just want to discuss 'hey guys, what do you think of the available practice materials? What kinds of scores are you seeing on x vs y vs z, which should I use?' they will a) get more responses, because their question has an answer and b)nobody will have to sort out 'hmmm...what similar question did OP actually want an answer to?' People should ask the question they actually want answered, both for their sake and the forum's. I don't think it's wrong to nudge them towards that.
Also, this way if anyone did give a concrete answer, there'd be a little handbrake in the thread going 'hold on, that cannot be right, how does this person know what they are saying is true?'
