I do!
I think finding a good stone for tomonagura is even harder than finding a good stone for honing, though.
Anyone wanting to cut tomonagura on the cheap, if you have a workshop and a vise, find a rigid frame hacksaw and a lenox 18 tpi bimetal blade (the 18 tpi blades don't have wavy teeth). You can cut several stones on one blade, and it's reasonably fast.
At any rate, I don't like hard tomos that much (something a step off that will shed its particles is a lot nicer). I always feel like if I give a hard one to someone, they won't be able to get slurry from it without crosshatching it, and some people probably won't be up for that. Hard tomos are often aggressive if you get a lot of particles free (maybe the particles stick together for a while and gradually break apart). The softer stones that are out in droves (shoubu, etc) are often a step off of true fineness (they finish a razor, but have to clear off more than a good tomo).
