I third the Reign of Fire.
Remember last season Storm had two ball lines (thunder and fire) that they merged into one this season (just the thunder). The new CAM core in the Reigns is basically dead in between the old Fire Line core and the Thunder core with the same cover. The Reign of Fire has the same cover (R2S), the same finish (1000 abralon), and the same RG at 15 lbs. as the T-Road Solid. Add in .002 additional differential and you have a ball designed to roll almost the same with just a tiny bit more backend pop.
