If you are going to run Schumacher, I would say yellow compound. Blue is really stiff, and only good for really tall astro or grass. On our track the Mini Pin offers the most traction, but is really edgy. Most of us have the outer 3-4 rows of pins ground off with a dremel. The Mini Spike makes for a easier drive and much less chance traction roll. I CA'ed the outside edge of my fronts to take away a little more sidebite. dBoots Nanobite's seem to be right in the middle, offering the traction of the Mini Pin, but the side bite of the Mini Spike at our track.
