Across 2 different threads, this question has been bumped 6 times despite getting some helpful responses. This means people either don't know or might not wish to add any more to what has been said.
If a question is unanswered after a few days, then bumping may be okay, but repeated bumps after just a few hours is, I think, is too much.
I like fid02's answer, so I'll mark this solved and lock it for obvious reasons.
