Those doval rings can be horrible to set up. In terms of front mech alignment. This is tricky on most oval rings but I find doval the worse because they aren't totally flat.
I seem to get on far better with the oval outer ring. When I'm climbing steep stuff at lowish cadence I don't like the oval little ring.
I've had q rings, osymetric, and now doval.
Q-rings = too little ovalality to tell much. Nice little ring for climbing.
Osymetric = great when under constant torque. But the sharp decrease in effective gear is uncomfortable when you're Pootling. Not great for low cadence climbing. Although taking a 38t little ring to the alps was stupid regardless of shape.
Doval = in between the 2. Less quality in manufacture though.
