I have a blox ball knob with a short shifter, and I flipped the retainer ring upside down and I think it sits lower on the Rogue short shifter.
Short shifter helped as I lost a bit of height
IMO - I dont like a ball knob with a boot that sits against it. I've always felt a ball knob looks better with a low boot.
something about this doesn't look good to me
but either a low boot or some sort of finisher will help
