im glad to try remove the pops and clicks for you too, I just bought Algorithmix RenOVator for Sequoia, and id love to use it. It is one of the best around for this sort of thing(and better be for the money I spent on it!), so if you dont like the wl results, id be glad to help out. Of course if they are every few seconds, it is probably a lost cause.
