Shock oil

[GorillaMaxx360]

I have a issue i think you guys can help me with. Here is the problem. When i drop my truck from about 1 and a half feet on a hard surface it absorbs the shock. when i drop it from about 3 feet the truck bounces. when i drop my truck from about 1 and a half foot on carpet it bounces. I will be getting the gmaxx suspension, but right now i am using big bores, stock oil that it came with(don't know what weight it is), stock springs, and a ride height of dog bones level. I thought i would need heaver oil for my truck not to be so bouncy. I want this truck to have a shock setup worthy enough to jump at a off road track but yet not to stiff to bounce with and street race. It this possible and what oil, springs, ride height, and shock angle do you recommend for this to work. (i am aware that i will have to change the shock possessions to allow for on-road racing, so when you are giving your opinions just base them on off road racing, but let me know what setup would also work for on-road.) thanks guys
