I have BIAB v12b and I must say there is not a day passes that I don't use it.
BIAB is also great for making Pad Riffs for my 9000Pro.
I play at home for pleasure and download to try a lot of free programs,some of them are very good. How often we purchase a program only to find it does not quite do what was promised.
BIAB & Power Tracks are excellent and produce better print outs than many of the more expensive sequences Cubase & Cakewalk can do.
