I begin to import the tracks into Sonar audio tracks. Once there, I save it and then begin the editing and mastering process and this is where I add my own guitar tracks, mandolin tracks, and vocal tracks


In my experience, I find it's better to stay in RB a little longer.
If you can start recording your new personal tracks in RB it leaves the option open to change a Realtrack or two, or even extend the song and regenerate where needed. This flexibility comes in handy sometimes.
I only move out of RB once I see a reason to. But I tend to stay there longer in the situation you described. Recording new tracks alongside Realtracks has not been an issue here.

I do not work here, but the benefits are still awesome
