It's been several years and you are still using that buzzword; I mean, it's _so_ 2010... Should've moved on to whatever's in this year... Incidentally, minors are 20 bit and majors are 12, but don't let that stand in the way of righteous indignation - what's mere facts when one is having discussions in context, presumably leveraging synergies all along...
