i just got into the rc world....

i have a eletric traxxas rustler that i droped a new 11T motor and 8T max speed sensor in.
it is fast but only have ran on the road, and jumped a few things.

i am looking to go nitro. I was wonder if i should get the savage X or a 1/8 buggy?

if i should get a buggy which one should i get?
