Since I mix with a lot of analog outboard inserted on my PT tracks, I'm careful to maintain a semblance of unity gain structure as related to the analog world. Otherwise I'll end-up overdrive the input stage of my outboard or having to trim down all my track level with a plug before it reaches the outboard. Anyway I don't like mixing with all my faders at -20 where there is no resolution to do fine moves. In 24 bits with good to great converters, I don't feel the extra resolution I'd gain from trying to kiss 0dBFs on every track while recording is worth the hassle. (Plus I don't like to soft-limit or to get over's.)
