"At the source" 100% agreement. There are quite a few problems with RealTrack when it comes to clicks, clangs, squeaks and worse. Almost all can be managed and "work arounds" abound but getting it right at the source is key to a good workflow and good result.
It's obviously cheaper to employ a software/code writer to fix some of these things than it is to hire a player, engineer and room to get it right though.
