Congrats Electrolyte! I've been using that same Cobalion set, actually, except with Stone Edge over Taunt. (originally saw it in the Creative movesets thread) I've used it on a sort of VoltTurn team, forming a core with Genesect and Landorus-T. I've got Lead Terrakion (who has Taunt, hence why I don't have Taunt on Cobalion; LO Latios for my main special threat; and Mamoswine.
Also, I think the thread title needs to be updated; post 170 isn't anything significant.
