This is an interesting thread. I have chucked no end of these things out, having buggered them up without ever actually managing to play one of them properly.

If anybody gets a surefire answer. I'd be interested to hear it. I don't think they are cheap at all. I've tried soaking them and something always sounds clogged afterwards.

is it just me, or do they go unsavoury looking after a bit? They always look as though you might catch something off them.
