I've always done four and five hour jobs, with the band or single. Depending on the mood in the room, I will or won't take my "scheduled " breaks. I won't stop because the clock says it's time if the place is swinging. There is always a point you can stop. I have (had) a system that took too long to setup to make 1 hour jobs worth it after travel also. I am looking at compact setups now; I like the Maui11 & 28 Frank has.
