My experience mirrors Doug's (ie. mono mix having less noise than
either channel alone).
However...

A few questions about the Mousetrap/Front End's approach to
groove wall selection:
1. Does selecting a single groove wall increase the groove wall
noise, since presumably you no longer have the random groove
wall noise from the opposite channel for some cancellation
when mixing to mono?
2. Is the transition between selected groove walls audible?
In the digital domain, when copying an undamaged groove wall to
replace the opposite damaged wall, distortion from the damage is
indeed reduced or eliminated, but the groove noise increases
substantially when compared to the usual mono mix of opposite
groove walls. In addition, there's some extra effort required
to make sure the transition is done smoothly so that the increased
groove wall noise is less abrupt. The trade-off between less
distortion and more groove wall noise is not always obvious.
I find that I don't resort to groove wall selection in the DAW
except in rare cases.
Just curious if the Front End has found a way around this signal
versus noise dilemna when performing groove wall selection.
