All are 1/4 except Denton. Little River can be either. If your faster than the 10 sec range I recommend the 1/8, on the big end at this track it is a nascar turn.
Little River Academy is a GREAT little track and we've had a Buick Bash there in the past, but it's pretty small for anyone who's real fast with no brakes Don't get me wrong though as I'd LOVE to have it there, being that it's only 30 mins from my house! Texas Motorplex is nicely located for many folks and can hold a HUGE crowd!
