Actually, I hate to shred whatever geek cred I may have here, but I haven't seen (or heard) Puggo Grande. However, I suspect if it were noticeably better than Belbucus, some of our audio heavy-hitters would have synced it by now and made it the default mono track for preservations.
I'm really not sure how a "best of breed" audio track will sound. It may be more of a Frankentrack than anyone cares to listen to as more than a curiosity. Especially with me doing the editing ;) We'll see.
I'll also happily step aside if someone else wants to jump in and do this. I've just always felt like I haven't given the mono mix the respect it deserves for a long time, and this might help change that.
