Ha... not sure what to tell you there... perhaps, judging by your signature... that you've gotten used to some big ol' hydraulic disc brake reservoirs sticking up there? It's funny though, because now that I've been riding the 11spd erogs for a few years, the 10spd ergos do feel a little small in comparison. Probably just a case of we get used to something then anything different might feel a bit off for a while, or you just never do adjust to it and go back to what you do like after the experiment is over.
But overall, it looks like you're almost there. Nice!
Most of my bikes are Sram mechanical, no hydraulics. Shimano finds it's way into the mix from time to time but lately it has been very much second choice. The last time I rode Campy, it was with down tube shifters, although I have done a few short spins on recent Campy equipped bikes (liked record EPS). Perhaps I'll be fine with the Ergos pointed a bit more skyward. Your bar/shifter arrangement is how it ought to be done but that won't work for me unfortunately. As for switching...it's an Extreme Power. It must have Campy on it. Shimano if the situation becomes desperate. But Sram on a "vintage" Colnago. I don't think I could do it.
And we haven't even started to talk about that thumb button which is only near your thumb if you move your hand off the hood.
Does the emperor have no clothes? I need a few hundred km before I can come to any conclusions.
When we ride disc brakes the whole deal of braking is just like a leaving a fart. It happens and then it's over. Nothing planned and nothing to get nervous for.
