Unless you are riding a steel bar it would be best to replace them every couple of years if you you are riding them hard such as racing. Both carbon and aluminum bars WILL fail this way. What is the design point for bars a couple of million cycles? Although carbon will usually fail from a notch sensitivity before fatigue from what I have seen.
I think your choice of Pro Ergosum is a good one. Very glad to hear you stayed upright. Did you pick up a lottery ticket?
