Well I'm going with the Smith Bros. adjusters. My current springs are only 365# open with a mild SFT so I think they should do the job. I don't know what adjusters RAS uses on their rockers but in changing all of them.
A good buddy(10 second GTX) gave an old Crane adjuster to get me through the weekend at Norwalk up
