IMHO-the PCR would be better. the PBS -pivot ball suspension -has more weight to it and more moving parts wich=more breakage. if you can take a look at both of then in front you will see the diff. 2 guys at the track had these when i got my hyper7 (c-hub) and they were breaking all the time. and if you are just starting then your gonna hit something and have some breakage. they are tough bugs i didnt break hardly a thing on mine. i just couldnt stand the motor(8port) it came out and i put a v-spec in. and yes alex i can tun and break in a motor you better check up on the starter box as well-i heard they are weak. try to look up the Mayhem they are a great bug for bashing and do great at the track. you can get them w/ the .21 sportwerks and i know for a fact they whoop butt. they also come w/a digi JR XS3i radio. and a roto start wich is easier to hall around if your gonna bash.
