If you can get a rear brace wire on your gear it will solve alot of problems, open out the bottom of the pants so theres no way the wheels can foul on them during a hard landing.
I used du bro big wheels (air inflatable ) & have them at a low pressure, this stops any large bounces.
Struts are from unitracs UK they are oil dampened, as well as spring ( 170mm standard folked ).
