+1 on that!
Using compact 10speed 105 currently on my steel EL-OS, it's a really nice group, shifting is pretty nice, effortless on the hands, brakes are solid, they don't bend like 10 speed Centaur for instance. I could be picky and say shifting from bigger to a smaller sprocket is somewhat clunky, but in the end it works awesome. Shifting from smaller to a bigger sprocket is smooth, both on cassette or front drive. Also, tidy cockpit with under the hood routing.
