As stated above I would like to use the DT instead of the norton 8k in the 4k/8k pyramid. The problem is I'm starting at the aggressive side if the pyramid (25 laps). I've read that on the welsh (?) stones less is better. So how would I rearrange the pyramid to accommodate the DT.

I may may be playing with fire here, mixing naturals with synthetics. But I've had really good results from using the hones from AJ.
