Juggler, as someone close to your age, my view is that a lighter bike is always appreciated and enjoyed.
especially if you will be using more g for unloaded or lightly loaded rides.
many options out there, and many of them with higher front ends so reasonable riding positions.
low gearing on even a lighter bike is important, especially if you even end up doing hotel tours with two rear panniers and a handlebar bag, just makes things easier on your knees.
