For those with an aggressive setup, it is not comfortable to ride at the bar ends either. Tri bikes are always annoying when it comes to having to move between shifters and brakes (which is why they aren't great for hilly terrain). I see many people on TT/tri bikes who grab onto the pads on the aerobars when they are trying to relax, because those are the easiest to reach compared to staying aero or moving to the ends. The pads are also higher up than the flat top of the base bar.
