I'll point out that the Manson Supreme appears to be amlost identical to
the Rocna, yet is much less costly. I have no idea how there aren't
patent infringement lawsuits between the companies. Lloyds of London
was sufficiently impressed by the Manson Supreme to certify it as a
"high holding power"anchor. I have no personal experience with it, and
know no one who has one, so do what you want with this tidbit.
