I'm with you there Trevor, the SM60 is a nice choice, I wonder is it worth going for the 90, some say (and with good justification) that the extra aperture isn't worth it in this occasion, I'd love to see a side by side shoot out between those 2.

Carrying around my 20" obsession is going to kill me,
but what a way to go.
