Hip and knee angles are one of my concerns with this. I can report that with a higher bottom bracket and matching the pedal spindle to seat dimensions between my two bikes, the top of the 200's are 40mm higher than my 180's. Cables should get installed this week. Photos of my fitting process with details of knee realative to pedal spindle, hip angle, etc. will follow.
One of the proponents I e-mailed with described having to concentrate on keeping his rear down when standing on climbs for the first several weeks. He just wasn't accustomed to his feet revolving through such a large diameter and had to relearn the degree to which his knee and hip needed to flex.
You might try pm'ing laxpatrick. Or, go look at the thread about his Gunnar build. I think he commented on leg flextion as well.
