I'd also say 105s. The replaceable top plate is nice, but the bigger advantage IMO is the wider platform. Which is really important for my 13EEs.

Best price I've ever seen is here: http://www.ribblecycles.co.uk/sp/roa...ls/SHIMPEDA835

$46.10 if you spend more than $72.50. So toss in some tubes or some Assos chamois creme.

And my set came with the little reflectors for under the pedals along with cleats. If you don't want the reflectors, eBay or CL them and get a few $$ back.
