I wouldn't advise using the Frog on such a heavy arm. It is a medium compliance cartridge, van den Hul's reference arm is an SME V with 11g effective mass. His test arm in the workshop is the Technics EPA 100 which has en effective mass of 12g.
You run the risk of the suspension collapsing prematurely.
As an aside van den hul will tweak his cartridges to match the arm used. I installed a Colibri custom made for the Kuzma 4Point11 at 18g, but personally I would not use a vdh ( even custom built ) with an arm with effective mass any higher than that
