I don't mind a shallow-drop, short-reach ergo bar, but I've fallen in love with my Deda Newton Shallow handlebars. Classic bend style. I find I like all of the positions on the classic bar better than the typical ergo bar. I've also found I'm more comfortable on a 40cm (c-c) bar than a 42cm (c-c) bar. My shoulder width would put me on a 42, but it just feels like I'm reaching out to hug the ground.
Considering ordering the S-Works Classic handlebar, seeing as it will drop some weight and it drops a few millimeters off of the reach. Also interested in Fizik's new "Snake" style bars. MIght have to give them a try if the price/weight is right.
Bottom line, play around with various shapes/dimensions. I purchased my Deda's off of Ribble. $60 for a set. Considering they sell for $60 on eBay used, I decided to pick a pair up and try them. They haven't left the bike yet. Before finding this price, I was considering purchasing a set of used 3T Pro Rotundos.
