Hi Brian,

I've had success with a few different models. Very much dependant on the cartridge you're running of course in order to maintain the best compliance (combined total weight of headshell/cartridge/tonearm).

If you're sticking with the same Audio Technica carts I believe the standard headshell is pretty much the best match. I've tried a few but anything between 7-9g seems to be about right.

Personally I also quite like the Ortofon SH4's, they are a tiny bit heavier but still work well and look very nice.

For some of my other carts I also use this generic machined aluminium headshell.

Lastly these are also very decent for the price, work well if you have a slightly heavier cart as they themselves are so light.

Not a huge amount sonically between them although some just sound better with certain carts.

More a matter of aesthetics but fun trying different ones anyway.
