If he wants good grip, Bridgestone S-03 (not sure if it's the same as G3 you mentioned) or Goodyear F1 GSD3 are the way to go, alternatively Kumho MX or Falken 451 if he's on a low budget.
Falken ST-115 is more geared towards comfort and very low noise, but doesn't offer as much grip as the 451 or others I mentioned.
Don't know anything about Goodrich Sport you mentioned.
