Good move Alex, I'll add a couple of links below.
I'll be bringing both of these prints 1 & 2 to John's at the end of the month. Both split grade on Ilford Warmtone. Hard to tell too much from the scans but they're all about the midtone separation which was quite easily achieved in both cases.
Of course there are many ways to achieve similar results but midtone control is simple and precise using splitgrade techniques.
