For a proper internet fitting, we need a shot of you on the bike. 😉
I imagine that if you regularly ride a recumbent, reaching for drop bars will feel odd. Nice build on that Miyata by the way. Find another larger one, put drop bars on it, and when you are not riding with your wife on the tandem, only ride the new bike with drop bars. Your body will adapt.
