[quote Anyone use the goove and wheel M&P's?[/quote]
Sorry, don't know what those are...Could you explain?
I have a marble, a wooden and a lava rock mortar.
Have to say I use the molcajete the most.
Find that the marble and the wooden ones are too smooth for most jobs.
Have to admit though, I've never tried to smash a single seed on its own, it is always a mixture of them, or with some wet stuff.
Marble works if you have more seeds, different sizes and shapes.
The wooden one is beautiful, but...supposedely it is traditional thai..Must be my falt that I can't find it useful..
Oh dear, someone has to teach me
