Budget Wheel Dilemma

I'll explain my dilemma if you want to entertain my rambling.

I purchased a new cyclocross bike last year as my multipurpose road bike. I've used the bike for commuting, group rides, and several triathlons (sprints and an Oly). The bike came stock with Shimano WH-R550 wheels. Although I haven't had any problems with the wheels I've always been a little leery due to the low spoke count, commuting use, my weight (220 lbs at purchase, 185 lbs currently), and poor reviews. My plan was to ride the wheels until the first sign of problems and then replace them with some 32H CXP33s laced to ultegra or similar. But the wheels are still as true as the day I bought them.

Since I had so much fun during my first season of tri's, I've decided to build a budget tri bike. I've been trying to decide whether I should:

a) Buy some handbuilts for the 'cross bike and use the WH-R550s (with rear cover?) on the tri bike.
b) Buy a new set of Mavic Aksiums locally for $200 and use them on either bike.
c) Buy a set of lower end aero wheels for the tri bike.
d) Shut the F$%# up and just ride my bike.

Any thoughts are appreciated.
