Jannsens elite heims are aircraft grade aluminum uppers and chromoly lowers with kevlar teflon injection. They come anodized with boot covers for a mere 329.00 a set. I don't know if fireball makes them or not. I understand that some will wear out faster depending on material used but when you said people were getting hurt with their heims, was kind of misleading. All heims will wear out, it's our job to make sure they are in good operational condition. If you crash cause your heim is worn out, that's your problem. If you crash due to heims snapping left and right, that's a manufacturer issue. I was under the impression that these units were causing accidents due to breakage not wear. If we want the best heims, there are titanium bodied heims with stainless steel sphericals. I don't think anyone would want to pay for them though.
