For some reason I've gotten to where I do use separate tracks for my verse & chorus, but not each one, I'll just have one for verses and one for chorus'. I do like the control it gives me on volume levels.
But, now that I've started using Reaper for mixing and recording any live tracks, I'm not seeing the need as much since you can put splits / in any track and then have level, panning & fx controls over any of those splits in the track. (very cool) Once you play with the program for awhile (OK, 20+ hrs in my case) and do a little referring to the manual, it's actually pretty user friendly and very stingy on CPU usage.
