Question cannot be answered. From a pure cost-benefit perspective, probably not - how much money are you going to make with the carbon wheels vs your current wheels? What is the payback period? Since I only ride for myself, and I'll never make a dime from riding, the payback period is infinite. Now if you take other factors into consideration, such as personal enjoyment, or giving you an incentive to ride, or even aesthetic considerations, then, well, only you can make that call.
