Currently using rs685 on my road bike and rs505 on the commuter and it's annoying as the rs685s look nice and work fine but the rs505 are the ugly bulbous lumps bolted on to the front of an otherwise nice looking bike but they work (and more importantly FEEL) amazing! Hood shape is awesome especially for climbing - bigger lever blade is more comfortable in the drops - just don't look at them as you will turn to stone.
