If that is proper way that JJ's should be maintained, then it should be taken into account when buying JJ's.
There are plenty of posts claiming that nothing must be done for years on a JJ (IE I haven't taken my joints apart in 10 years). The one year maintenance cycle is not explained by Currie nor is it common to see on this forum on suspension discussions. The more common reply is "Currie/Savvy is best, get JJ's". I also don't think taking 14 joints apart every year is something that is common with a quality joint.
I'm running Currie arms, but I also have no reason to believe I would achieve any worse results with most of the other aftermarket arms on the market. And if it isn't clear, I'm just trying to challenge some of the echo chambers that rattle around this forum sometimes
