Speaking of movements being large, the throw on my 105 5600 set was unacceptable, and while not lacking in dexterity, I had some minor issue with the integrated levers canceling each other out on an upshift to the big ring. I sold the entire bike. Baby/bathwater, maybe, but the shifting setup on the 9 speed Microshift is far better, IMHO. If Shimano had thought of the upshift lever for the rear on the outside instead of on the thumb for Sora, Microshift may not be in business.
