The biggest problem with a diesel on deceleration is lack of back pressure. If you cannot adjust valve timing (Jake brake) or restrict the exhaust, it will feel like a gasser with the spark plugs removed. I think you will like the feel of an EB setup.
My current truck runs 4.44 gearing and 31" tall tires. This results in great performance up to 65 mph (which I don't exceed). If you tune your setup with the proper axle RP ratio for your desired top speed, you may find the other gears fall in place better for your use. I read about many guys locking out 6th or 5th when towing which reduces the number of gears they have available and creates larger splits - I use all six of my gears when towing and don't use my truck unloaded to need anything taller. This gives me closer splits since all the gears are usable under load.
