My chorus 12 front shifting has been great. Even with my small hands, shifting to the big ring is no problem.

I actually think the front derailleur shifting on my previous 10spd Record was better than my Chorus 12spd...I find I require a big shove to get into the big ring, sometimes it takes several goes as I'm surprised by how heavy I have to shove it?

I've previously used 39/52 only, I'm using a 36/52 now which I'm not happy with at all. The 36 is useless for my area but I suppose I'm using the big ring more than ever! 😉
I felt the 12s was about equal, but I also noticed the increased amount of throw needed. The added "click" in the 12s system means you have to get the FD all the way out to get a complete shift. With my small hands, I have to be on top of the levers to shift the front. But, I'm normally on top of the bars already when I'm in the small chainring. You do get used to it quickly.

FYI, I switched two mechanical and one EPS bike to 12s about a year ago, and I'm very happy with it.

I'd never be riding in the hooks and trying to shift from little ring to big ring. I always make that shift from the hoods.

I've done it occasionally when hunkered down and riding into a really bad headwind.. but once in a blue moon..

That is what is really nice about the drooped thumb levers

Shifting from drops is simple

For me the Chorus 12 speed front derailleur does not have that problem:
it seems to shift even better than the 11 speed version and does not require more effort.
Moreover, I was surprised how easy it was to set up -- I guess I got lucky to have it working on the first try.
In "exchange" for that I cannot get the rear shifting right...
the chain is either noisy in the small ring or in the big ring depending on the adjustment.

I agree, the throw seems to have increased?

I know I have everything set up correctly, it's a big shove though!

I don’t have that problem reported above shifting my SR12 from small to big ring front when in the drops. No problem whatsoever. And I’m not a big hands guy, I’m a size S on the border to to XS in cycling gloves. Good for me since I spend 40-60 % of my riding time in the drops

I have Record 12 speed and I cant seem to get my hood position dialed. I am getting a lot of pressure on the palm of my hands. I have 3t superergo bars. I just cant get the transition of bar to hood to be flat. So I am getting a bump. If I were to slide down the hood to make transition flatish, the hoods are angeled too far down and it is a different type of uncomfortable. Anyone have any pointers or tips?

Issues with shifting may simply be the cable or cable routing. I have two bikes with identical (shimano) group. One is much lighter shifting the FD than the other.

Lower the levers on the bar to get a smooth transition and then rotate the bars up to get the hoods at the right height?

I have 3T bars. I have a little bit of a bump but not nearly as prounounced as yours. You also seem to have 3-4 layers of tape under that area. Try and reduce that.

The bars are rotated too far up. Rotate them downwards and then move the shifters a tad up.

Can you post a pic of the bar including the lower part of the bend?

Looks like the lever is too low on the bar but it’s hard to be sure with only partial pic.

I have played around a lot with bar rotation and lever angle and just cant get it. It is driving me nuts! When I do get a semiflat transition, the bars are too low. I think I may just have to shim the hood angle with some extra bar tape to ease the transition.

You still have the possibility of bringing the levers closer? I'd try that, lift the hoods a bit higher up, and maybe also the rather non-WW trick of putting a piece of bar tape at the notch between bar and hood to smoothen the bump.

That said (and I fancy Calnago would have nodded): Those 3T bars are more for Shimano than Campa because the bends are so flat and the bend radius where the controls go therefore is quite small. I've had success with the Deda RHM and FSA Compact shapes with Campa, using the latter now because I like their flare.
