I always liked the Hasselblad 150...and the 50, although the 40 is
gorgeous if you have the $$$.

An 80 isn't going to be wide enough for large group shots.  And I've
found that the 150 is too long for most general wedding shots.  I use a
60 as a wide-ish "normal" lens.  Pictures taken with it don't have the
wide angle "look," but it's still wide enough to handle groups in tight
spaces or for getting a nice full length of the bride and dad coming
down the aisle from 7 or 8 feet away.

For my "long" lens, I like the 100.  Great for 3/4 portraits,
environmentals.  Used wide open, the background is nicely soft.  Also,
it's the perfect companion to the 60.

For those times when you really need a wide wide angle, I opt for the
SWC.  Although, a 40 will work as well.

Also, get some soft focus, diffusion, special effects filters, etc.
