I decided on balance that there were not enough pros for my kind of riding, as the cross top levers get in the way of holding the tops for climbing. They remain popular with cyclocross riders and people doing more technical off road stuff than I do on drops, because the tops position moves the CG back compared with either drops or hoods, which is handy when you're braking on steep downhill sections. They are probably most effective with wide bars, which again is a compromise I found I couldn't live with, otherwise the grip on the tops is too narrow.
