I have it down pretty good after quite a few years.  I very seldom tandem anymore.  I have a center seat yoke from Spring Creek and one of their composite double bladed paddles.  I did a two week solo in WCPP in 2017 and nineteen day with brother last year.  I still used the two blades as it's easier for the bow guy to fish while I paddle.  Works great.....for ME like you say.  Thanks for the inputs!
Later.......Mike
