Actually, there is only one right answer - the carb you have now.
It is a good piece, just give it what it needs and it will give you great performance, decent gas mileage (better than any other carb system out there), and pass emissions.
See the tech articles for what the carb may need to do its best. Some simple adjustments and secondary rods/hanger tuning are typically all that's needed.
