Count me in with the classic group of users---those mainly using traditional styles and real tracks. I'd love to delete the majority of styles in my 2013 BIAB---to streamline what I have to wade through. However, I'm sure with deletions, I'd mess something up. It's working so well, now. I always want the latest improvements to the basic operation of the program, horse-power and all that; but, only a select, narrow group of styles for the market I play. And, at my age, that's not going to change, for sure.
