This is what I don't understand; why are you guys tracking in one DAW, and then swtiching over to another just to record, and then bringing it back to another?
It would make sense if you have all your tracking done in DAW, and then export the files to the other, but why would you do these seemingly redundant actions for one track? What's wrong with tracking in the DAW you're mixing in? We've established they both sound the same, and the work flow portion seems to be negated by the excessive work of exporting and importing songs into your other DAW.
