This is going to sound like I am making fun of the whole thing but bear with me. You won't have hand problems riding no handed. You won't have hand problems riding a unicycle. You won't have hand problems sitting on back seat of a tandem reading a book. Hand problems start when weight is on hands.
It is possible to ride for hours pulling and only pulling on the handlebars. Pulls all the places nerves might pinch apart. Also delivers lots of power which is a different issue but closely related. Grip bars lightly. Never a death grip. Only time you need a solid grip is when braking. Put some weight on the pedals. Enough weight on the pedals you'll have no hand issues and no saddle issues.
