Thanks very much. I think you settled my "GAS" (Gawd... how I hate that expression) and now I'll try to find one to rent or borrow first. I'd like to try it with monopod before shelling out the money. Maybe I'll continue shooting the 150 and crop... who knows?
How about Hasselblad Acquisition Syndrome?
Have/had Mamiya RB, Rollei 6003, Hasselblad, Nikonos, Canon EOS, Leica R, Fuji Instax...and some other stuff
