How about spring tension on the gear struts?
I'm thinking of cutting a few coils off to lessen the pressure, especially the nose gear.
May reduce the amount of rebound energy that keeps it bouncing?

Mine is nose heavy. but, If I lift the nose it will stay with the tail on the ground.
If I add about 16 ozs to the tail I can get it to balance on the CG.
May make the nose wheel kind of light for steering, although the high mounted engine does push the nose wheel down at full power.
