Thinkin' about a Super E
I put an S&S E on my bobber, just because I wanted the teardrop air filter cover. I don't have enough experience with different carbs to really form an opinion, but the S&S feels far snappier to me than the stock CV carb. The apparent snappiness is almost certainly also related to the fact that the completed bike is about 130 pounds lighter than the stock bike I started with.

I experienced the same when I put a Super E on both of my softails.

Been happy with my Super G, but then I haven't had to play with it. There is an oddity in that my S&S 107" engine came with a G, whereas the successor 111" comes with an E. Both engines give similar wide torque curves and performance numbers. When newly run in mine gave 107HP.

Since most people don't spend a lot of time at WOT S&S switched to the E.
Above was told to me by the S&S tech I spoke to when I asked him why the change.

Thought I read somewhere the Super E isn't very adaptive when it comes to atmospheric changes. Meaning basically it'll start running rich when driving in mountain areas, or lean on sea level, depending on where it is tuned to. Not sure if this is the case though, I don't have one

That is true, but also true with the HSR. CV is less afflicted on account of the slide only going up based on the flow of air going into the venturi, which does not correlate directly with the butterfly/slide carbs because air that's less dense due to altitude inherently will have less volume, therefore lift the slide less per a given throttle position.
It also doesn't bother me.

Plain and simple what does your pump flow@10"hg... @ .100", .200", .300", .400", .500" and .600" lift? Once you figure that out then put on a carb that can match the flow rate of the need..
