Does 21g seem high for effective tonearm mass?


Hi there, I've been looking into these somewhat popular Jeclo tonearms. Actually the 10" liquid dampend unit SA-750e. I've got an email from Jelco and the effective mass is 21grams. Does this not seem shockingly high compared to nearly everything else on the market these days?
I plan to mount a Sumiko Celebration on it but I'm not so sure about the match. It seems this arm may be limited to cartridge choice and that would be too bad.
If anyone can shed some light on this it would be appreciated.
My other options for arms of course would be the Rega/moths, Hadcock and I can get a pretty good deal on a VPI classic arm.
This wasn't supposed to be confusing at all as I was taking a step away from my ET2 and trying to simplify my setup. Now it seems I've opened a can of worms

The Jelco headshell is a perfect candidate for the drill. A lot of mass can be removed without impacting the rigidity by drilling holes. I can't remember the drill pattern or how much mass was removed, but IIRC, there were a couple of people on vinylengine that pretty successful.
IMO, the classification of low, medium and high mass arms seems a bit arbitrary. The goal should be to match a given cartridge compliance with the effective arm mass. Plenty of calculators around to help in matching.
