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.

That tonearm has a mass of 9 grams!

Put the information in this chart to find the resonance frequency of the arm and cartridge capability!

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
