I have a set of the HED Ironman Jets. Steve Hed and his wife are great! They are very friendly, and their customer service is great. I have had a few problems with my wheels, though. Twice I've gotten a broken spoke during an Ironman race. Once the carbon hub cracked (not during a race). When the carbon hub cracked, they took the wheel, tried to fix it, and ended up giving me a brand new wheel - no charge. I like my wheels a lot. However, the wheels do seem to go out of true and break spokes more than other wheels I've used. I bought my wheels in 1994, so they have probably made many improvements since then.
