it seems to me that these bikes seem to run better with a richer bottom end (had a dyno guy tell me the same thing after coming to that conclusion thru my trial and error)

IMHO for your set up Staffo I would probably go with the 45 pilots. the only down side is they will not help with fuel economy as they are always drinking thoughout the entire range (not just on the bottom end).

if you really, really like playing with the carbies I recommend getting the FCRs. lots of adjustment possibilities.
