I think rokman uses jj's. The tube is thicker than the curries and they are usually cheaper than currie.
I am with you though, I wanted the double adjustable lowers. With my 3 inch lift the stock ones are working. Adjustable were my first step towards belly skid. I get my lj at the end of 19, plan a build, then everything shuts down. Now it's all out of stock lol
