The Kennedy is way overpriced if you're into flavor. Have an authentic,,105usd. It's a well made topper, yet you can
buy a more flavor oriented dripper for half the price, Easy.
The TM, have clone & authentic can be used single coil with excellent results,22mm. Just use one A/F near coil.
Not on your list,, the NarDa is a spectacular flavor dripper. And mine is just a lowly clone..
