Thank you for all the replies. I haven't ordered anything yet.
I should have elaborated on my racing situation. About 7-10 guys i work with all bought cheap 1/8 nitro buggies and built a track in one of their back yards. We are having 30 yards of dirt/clay hauled in next week to build jumps and finish it up. Nothing serious, just a bunch of bashing.
I am checking out the .21's thats probably what i will be getting.
Once again, i appreciate all the input.
