A 1/4 choke barely cuts off any air. You need a plug chop after idle. If a 1/4 choke changes it, you just need to adjust that fuel screw.
I know people who have bored the motors and ported their heads and use the 78 carbs with 0 trouble.
People run pods with 4-1 exhausts and do not have to always rejet. So unless you are running a way open exhaust, pods, and have motor work done, the 78 carbs will be fine and will work better with pods than the 80 carbs will.
