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

There's no way that the Jelco SA-750e has an effective mass of 21 grams. My Zeta arm is 16 grams and is MASSIVE compared to the Jelco. Maybe they gave you the weight in some weird Japanese measurement?

Dear Alun: No, 21grs is on the high part of a medium mass, there are high effective mass tonearms in excess of 40grs.

Don't worry about before you mount and test the Celebration on it, after that you can decide if that tonearm is a good match to the cartridge and remember that the Jelco is a removable headshell design so you always can use not only a different headshell weight but a different headshell build material that can help to the Celebration shows at its best.

If you can change the headshell stock wires for the Ikeda S-50 that you can find through an ebay seller: 2juki, this sole change makes a difference for the better.

Regards and enjoy the music,
Raul.

Well I did some looking around and it appears that the headshell is already 12grams and is about the lowest I could find.
I'm gonna post another thread on my tonearm seach.
Thanks fellows!

Mofimadness, you read it right 21Grams, and you should see some of the weights for the Ortofon arms!
Now that said I did do some calculating and it will work with my Sumiko, but I'm having a change of heart and leaning towards the VPI 10.5i or a used Audiocraft AC3000. They both have similar features except VTA on the Fly by VPI. Also the Classic is a nice choice.
Decisions decisions.

Another choice you may not have thought of, is Origin Live. They have arms priced over a fairly wide range.
