I've been looking at the Z1 options and I'm not sure as to which would suit my needs more be it the 25 row or the 34 row. I live in TN so it goes from mildly to very hot here for probably 6-7 months of the year, pending month of course. I will be tracking the car at some point but didn't know if I needed the additional rows for cooling or if that was just overkill. Any input is appreciated.
