It's a medium.

I looked at 200mm 888s, was put off by their height. 180mm 888s might be OK, but I wouldn't personally go for 200mm. Never know, might be good. I got Boxxers for their low A2C height and their low weight, love them on the SX. Certainly raises the BB a bit, but the increased performance and feel of the forks far outweights the slight BB-height increase. Can take the DH courses without needing to fork (haha, ok not funny) out the money and put up with the weight of a full-on DH rig, love it.
