One last thing...don't go with the Hoosiers unless you are running Nationally...there's noooo point to spending that much dank for local events where there is no contingency to be won. Yes, the z214 will be fine in the C71 compound, lots of people run them because they are affordable compared to anything else...but running a 13" wheel will give you spec-v syndrome, where you run out of gear in 2nd on the longer courses.
