Have you ever tried a KC Pro Aviar? It's the same mold, but much more stiff. I bought a Star Aviar Driver a couple weeks ago. It's taken over most of my putter drives and upshots and has left my less durable Pro's for mostly putting. I think it's a great combination as the Star plastic will hopefully keep more of it's stability. I still have a couple well seasoned KC Pro's to drive and upshot with when I want a little less stability.
