I cannot fathom why people are honestly considering a defensive set and are excited about priority Roost. Talonflame has arguably one of the worst defensive typings in the game, terrible defensive stats, and loses half of his HP on entry. Priority Roost is extremely predictable and will cause it's death to be even more swift via the ever-common EQ.
Do what this Pokemon does best, kill everything it can and set up Tailwind. I really like the Lead set that JackofSparks posted too. It OHKOs Galvantula, preventing Sticky Web, and if the opposing Lead is a SR setter that Talonflame can't handle, U-turn to Xatu or Espeon.
Considering the bulk and x4 SR weakness Talonflame has, I think he would be most reliable as a lead. If your spinner/defoger dies, Talonflame is as good as dead too.
