That's good. If it is a single person and/or a prepared show RB probably has some advantages over BIAB. But in my case I can't predict how many improvised solo repeats we will need (people don't show, people change their mind about soloing last minute). I see BIAB as a must have at a jam. We use it to hold steady speed as well or test how well we are doing that. BIAB does the job well. I have never had BIAB abort at a jam. RB probably would not if it was just playing tracks.
