Rich, I think the only one really working on hard parts now in regards to cams,valves. Etc. Is Tadd. I could be wrong. It would be nice to have more options for the 6 leaker. But until they can compete with the CR the big companies won't step up. Tyler and I are working on getting his twins set up perfect for next year. Our goal is 11.99 on fuel in a crew cab. We have our work cut out. Letting go of the bottle for me is like letting go of the nipple. Not a chance. I love my 6 shots of spray. LOL.
