klem - interesting re the 500T. Easy to get hold of to here in UK. That said, I'm not too clued up on Dunlops and they've previously never floated by boat when I have checked them.. I know what you mean re Princes, don't why exactly but I've never quite got into the feel and response. That said, I like how they hit easy, big and spinny and like the grip shape a lot... hoping to be formulating my own thoughts on 100s shortly.
Murray - okay X10... I'll read up on it some more!... I feel like I've been there/done it re Pres Pro frames - unfortunately they are just beyond my skills to use properly. Trust me, I've tried.
