Yes, now that you bring that out you might have a point. Depending on the schedual if you are in a DCI line playing shows every day then that is the best idea. But if it was every weekend like a DCA/WGI line then there would be practice times to use chop builders for guys that needed to work on it.

I have played in lines that once they had their spot in the line they kind of took it for granted and the tech got a little sloppy and weak. Meaning they didn`t really work or practice to keep their playing where it should have been.
