As an 82 year old bike rider, have ridden several different types of bicycles, I can tell you that the three major point of contact on a DF bike will not really and truly make you comfortable. And that includes so called bike fits. Just to mention one other thing, on long rides holding you head up for long periods of time is a pain in the neck.
And yes, for the past 15 years I have ridden recumbent bikes and trikes for comfort. However do not forget all bent riders started out on DF bikes and rode them for decades, so we know the truth about DF bikes. Dont get me wrong they have their place in many situations, but comfort is NOT one of their prime attributes. Many of us when we were young and light could tolerate the discomfort, but when we got older and heavier the pain becomes more accute.
