Actually Superflux Lincoln has a rod out specifically for lo-hi downhill, LH-D80, LH-D90, LH-D100. I have not used it as of yet but was interested in giving it a try until I checked the cost of it, then figured if I was going to use it I would have to have new wps and testing($$$$) to effectively use a more expensive product, or stick with 6010's. Link to Lincolns page with the three listed above,

Been a few days so hope to hear from him about that in awhile, interested in giving them a run.
