I haven’t a clue about that particular groupset, but i do run microshift something or other. Just in case you are not familiar with microshift- the main thing is the way it shifts – push the big lever in to shift to a bigger cog on the cassette/chainset and push the small lever on the outside to a smaller cog. Brake lever only brakes. From the pics it looks to be the case on the arsis.
For me, this is preferable to the inside shift up on the sora, but not as good as tiagra, 105 etc upwards. This is because i can hit the mircoshift small lever easily when in the drops, but on sora it takes a huge thumb to do the same.
thats my twopence worth. I would recommend finding one in a shop to see if you like the ergonomics.
