Good for you old timer ;o)
I've only read good things about that racket so I hope it works out for you.
When you read the specs with its 315g weight, 107 head and low stiffness rating, its hard to find a reason why not to give it a go. Good for doubles I expect too, with that 107 head looming at your opponents, quite an intimidating sight I expect. And great that you got your grip size too.
Keep us updated with how it goes.
