Hey OldChipper,
First, welcome to C/A. We are a friendly group here.
Next, at your weight, from what I've read here time and time again, you aren't too heavy for most wheels, except MAYBE the cheapest entry level wheels. BTW, I'm 230 and ride FSA RD-60's. If I don't blow those up, I'll be truly amazed.
Finally, it is my opinion that you should ride what you have. You haven't had any problems - why assume all of a sudden everything is going to explode on you. Sounds like you have some really nice wheels. Ride them until you have problems, then worry about it.
TL : DR - Ride more, worry less!
Enjoy!
Now, with that said - smart people will be along shortly with good advice!
