yeah its kinda a personal preference depending on who you ask....on that chassis you are gonna run chuck i did try it with 75wt and then 30wt and then basically none but my springs were stiffer than the ones you picked up so you should be able to run oil maybe not very thick but you will have to experiment. when i was running droop on axial and tmaxx shocks i was running 65 all around after trying several combo's.
^^^yeah man, he is running revo shocks wich dont have much travel at all and when i ran them any thing thick at all even the 30wt was just too much. although i never drilled another hole in the piston wich would have helped but still its kinda hard to get travel out of that chassis with those shocks.
theres a few others that work but they are basically the same thing chuck. i liked the look of the revo's better is why i got them. yeah you arent gonna get much travel with that chassis but you should stay planted to the ground very well, i know it worked like a charm for me.
