Kamui's are the nuts! Best tips ever.
I am replacing all my tips with Kamui's, whether they need replacing or not.
Each designation (S, MS, H, etc) has excellent consistency, though each one is also harder than other brands of the same hardness. So a MS Kamui will be much harder than other tips called MS.
I use MS on all non-ivory ferrules, and S on ivory. No pads.
My first ones were installed 3-months (on my daily player) with NO mushrooming at all. For that matter, I haven't done anything to it since the Kamui's were installed! Oh, and they are not cut down! I can see the layers from across the table.
I have ordered from both guys who already Posted in this thread, and highly recommend both of them.
PS: Kamui's are not cheap. Buying 1-2, expect to pay up to $19.00 ea.
