I like drop bars with a short drop and shallow reach so all of the different hand positions are fairly close together. That way I have a fairly constant body position that is always comfortable regardless of hand position and I can use all of the positions any time for as long as I want. That way I can minimize hand numbness which is my main problem. I also like bars a little on the wider side as it makes steering more desensitized AND I have room for more junk to attach on the bar tops. I also prefer an anatomical bend and I use gel pads under the bar tape. The two main bars I ride lately are the Ritchey Biomax Pro and the Salsa Short and Shallow. The Ritchey bars are much nicer but are about 2.5x the price of the Salsas..
