Lets get this thread back on topic
I've now tested PL25 (EFKE) with Xtol (replenished) with excellent results. These intial tests indicate I can probably rate at 50 ISO for N development, but a bit of fine tuning is needed still before I have concluded my Zone system tests. A wonderful pint of Ceylon tea aided the neg processing.
Further tests with PL25 and Pyrocat HD will take place at the end of the month and I think I'll supplement the processing ritual with a refreshing cup of Lapsang Souchon, the smokey flavour of the tea excactly complimenting the warm staining effects of the Catchetol in the Developer.
As for me I have a large supply of Catchetol (also known as catchetin Pyrocatchetin) so no need for pyrotechics with cats.
