Weber vs Su

["R. O. Lindsay" <rolindsay@dgrc.com>]

Hi Gang,
   This is probably one those topics that has been
beaten to death but I must ask.  If it is really old hat or
offensive, please reply privately.
   All issues of originality aside, what is the performance
difference between the stock SU carbs on a '70 B-GT
and a Weber DGV?  Starting is better with the Weber
because it uses an accelerator pump but I am interested
in on-road performance.  Opinions?

Thanks,

Rick

PS: For reference:
    DGV = manual choke
    DGAV = auto choke, water temp actuated
    DGEV = auto choke electrically operated
