Super tacky up front for a little extra grip, and the 3C in the back for better rolling. If you're looking for a long lasting tire, definitely get 3C for both as Super Tacky will probably not last more than a full season.
I personally run a SuperTacky rear and SlowReezay front. If you have the money I'd go with 3Cs as they're the best mix of tyres. The SuperTackys will last a while and give you good traction, and the SlowReezays just stick to anything but wear out pretty quickly.
