Ok lets try this. How much does a spring axle go up and down?? How much does a torsion axle go up and down?? Does a spring have more travle or the torsion have more? Better ...

Torsion axles (rubber dampened) don't have anywhere near the suspension travel a leaf sprung axle has. Not to mention if the trailer is not perfectly level when towing one axle will be loaded more than the other. I would take the heavier duty leaf spring system and add a rubber isolated equalizer system then you will have the best of both worlds. More suspension travel and smoother ride.
