I love my Look Keos, but there's definitely a learning curve clipping in (probably with most other systems). It honestly took me over 3,000 miles before I could reliably clip in without looking.
ETA: Clipping in is easy. Unclipping is easy. Finding the pedal and tipping your foot to the exact angle that will let you clip in and not send the pedal spinning, all without looking at the pedal, takes a bit of practice. You want to be able to do that in a race and I assume you can with the pedals you're using now.
In your mount/dismount area you're going to be hurrying, jacked up mentally, distracted by other competitors and spectators. I'd stick with what you know unless you have a LONG time to train for this one and a specific reason to switch.
