Jerry,
The T4.9 is a great boat and you would be hard pressed to pass it up if you are considering one. Just so you know the most frequent national title holder in all the Taipan ranks sails a T4.9 Uni and when I spoke to him last he was the same weight as yourself.
No matter what you use the boat for racing or recreational sailing its all about balance and feel.
Sail them all and buy the one that has the best feel.

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
