The current 3 hole Antirock appears to have done away with the two loosest settings from the original 5 hole. This means you can't run it as loose and floppy as Jerry did.
I think the opposite, assuming I'm interpreting their instructions correctly?
I've got the original steel 5-hole Currie Antirock and run it in the loosest setting as well, paired with the stock rear sway. I like how it performs. Not sure if I can keep the stock rear when I outboard though... something I need to look at still
