Try to get to test ride both of these tandems you are possibly interested in.
At tandem #3 you will know which is the better for your team.
Have known Mel and Barb and Jack and Susan for decades, both couples know their tandems.
Mel may stock the Smooth and handles the Haka (built for Tandems East in the US).
It may be worth a weekend trip to the New Jersey shore.
You may want to consider the 26" wheeled Co-Motion Periscope . . . we had a custom Co-Mo that served us very well for 56,000 miles.
A tandem is an investment in your good health and life style.
What are you gonna do, wait til you get older to get the tandem you want?
At ages 83/81 we are on tandem #5. The current custom c/f tandem has over 45,000 miles on it and we still ride it TWOgether very often.
Pedal on!
