I figured, based on your signature as well i was wondering if you'd chime in!
My thought was that if I got the 60mm I would sell the 80mm. I would likely buy the CF version of the 60 and 150mm and sell both my 80 and 150 C lenses.
I have heard good things about both the 60 and 100mm, with some even saying that they're the finest lenses in the lineup. I seem to see the most recommendations for the 50 / 80 / 150 trio though so that will likely be the route I take.
