I got lost...but one piece of advice. Whatever you decide to do, you have to absolutely make sure that the aero bars are set up properly. And do NOT move the seat forward (assuming that your seat is OK now for your drops) to compensate for your more forward position in the aero bars.
Whatever bars you get, make sure that they are adjustable, fore and aft. In other words, you get an optimal body position (pedal stroke, hip bend, shoulder/chest width) in the aero bars...
You can't just slap these things on and go if your intention is to be fast.
Hope that helps...
