Not sure how many miles per day you want to put on, but typically the average tourists puts on 40 if mountains are being climbed, to 60 miles a day, of course there are some diehards that will put on 120 but remember I said average. If you're on a bike for just 60 to even 100 miles I don't see the real need for aero bars unless for some reason you're in a rush then the aero bars may be useful. I ride a lot of times in excess of 100 miles and never had the need for aero bars...but different strokes for different folks. Also keep in mind this being more aero on a touring bike is complete nonsense since you have panniers shaped like boxes preventing you from being aerodynamic anyways! The aero bars are more about for some being a bit more comfortable for resting a bit on something, but if you need to stop suddenly you have to move off the bars to the brake levers which could be a problem to do that quickly. Keep in mind that a loaded bike is more unstable and moving your body position into that type of position could cause handling issues you may not be prepared for especially hitting a rough spot on the road, personally after doing even a moderate weighted (25 to 35 pounds of weight) touring trips I would not want aero bars, they may be fine if you're doing ultralight or credit card touring, but not for anything over 25 pounds and definitely with no panniers and/or handlebar bag on the front. Just my opinion.
