I don't know if they had the 888R and 888RC specs mixed up. Does not seem like the 888RC should have dual HSCV while the 888R has HSCV (one side), SSVF (one side). Thats not the way it is now.
The current 888R has dual HSCV and the 888RC is HSCV/SSVF. I think that would confuse a lot of folks if it were opposite like on the site.
