Removable headshells 101


Due to the influence of Raul's thread on MM cartridges, I believe that some of us (perhaps for the first time), have acquired a tonearm/s with a removable headshell?
In my case, there was a vacuum of knowledge or information about what makes a good headshell and for the last 6 months a great deal of my time and effort has been expended in acquiring personal hands-on experience.
Perhaps a Forum to share experiences will help new adherents to this once denigrated (by the High End) segment of tonearm design?

Interesting. Do you have a favorite arm, or is it basically horses for courses? 
In another thread, Halcro talks about pairing plastic bodied carts with metal headshells and metal bodied carts with wooden ones.

Then there's this blog http://zero-distortion.org/micro_seiki_8000_mkii_koetsu_colibri_thoress_airtight/   that talks about matching a Koetsu and a VDHul with headshells and other tweaks to make them sound more similar. This is continued on a What's Best thread linked in the blog post.

Based on that, I ordered a Jelco HS-30 magnesium/rosewood/brass headshell that looks like the original Koetsu headshell to try with my Onyx and Rosewood.

@maxon,  I am not sure about difference between Jelco HS 25

and HS-30. Anyway I would never buy any headshell without

''movable 4 pin connector''. With this kind one can adjust azimuth

as well the stylus eff. length. This exclude wooden headshells which

can't accommodate ''movable 4 pin connector''. The screw which

need to tighten 4 pin connector in the headshell  has not sufficient

hold (in the wood headshell). Jelco is sold under different names with

different prices but is the best offer qua price-quality relationship

(+/- $60).
