Cartridge Headshell Match


I recently purchased a Technics SL1200 GR.  

I currently have an Ortofon MC Rondo Red mounted.

I plan on getting another Headshell and mounting a Benz Micro Glider that I just had re-tipped on it.  

I noticed some headshells have azimuth adjustment which would be nice but weigh around 12 grams. 

I can get a technics style headshell with no azimuth adjustment that weighs around 7.6 grams.

The Benz Glider weighs  6.6 grams

The Ortofon MC Rondo weighs 10.5 grams and sounds great with the stock Technics headshell.  

 The Benz is lighter in weight than the Ortofon by almost 4 grams so would that better mate with a heavier headshell?

I know this subject has been covered many times before but it still confuses me a bit.

donvito,

Thanks for the calculator link.
I’m assuming the effective tonearm mass includes the stock Technics headshell.

Most of the combinations of headshells and cartridges I have or may obtain calculate to somewhere between 8 to 10. Maybe just over 10.

Even if I use a 12.1g headshell with the Glider the res.freq. comes to 9.1

If I use the 12.1 with the heavier Ortofon comes to 8.8

Doesn’t seem completely out of whack.
I'm going to test this with the Hi Fi news record to see if the resonance frequency comes out to around 9 with the Ortofon/Technics cart. and headshell.  

Will let you all know what I find.

Thanks
Using the HiFi New Test Record the Ortofon/Technics combo I got:

Lateral  11 Hz
Vert.      10 Hz

Seems close enough.
I figure the Benz should work with pretty much any of the headshells that have been recommended.  

Either the Jelco or LPGear Zupreme w/azimuth adjustment or another Technics style headshell without azimuth adj. but won't know until I actually try one.

Thanks all.
