I personally would always take 410s over a 610 or 810... easier to work with, easier to fit into vehicles, more flexible for varying sized gigs. If 65# is bad, try an Orange PPC412 or OBC410. Both are around 100# 
I finally got promoted at work, so now I get to actually put in an order for a Superbassman setup instead of just drooling over this thread like i have for the last couple years.
Now my dilema is what exactly I want. Black and Silver, or Blonde/Oxblood, do I want the 410, or the 610? First world problems as you can see. I have been told the 410 sounds like the 610, but the difference to me is being able to pop the amp on top of the cab and roll it in, vs carry them seperately.
Then there is always the idea of adding a 2nd 410 later... See what I mean, I do love how the Head looks on top of the 610 though. Astheticly that would be my choice. But one trip from the car ( in most cases) seems much nicer to me then 2. 65lbs is no joke either. hrrrummpff!
