Using Pryocat HD with Efke IR820

Started shooting Efke IR820 120 med format with EI around 6. I use a jobo processor and have been happy with using pyrocat hd with Delta 400, TriX, etc. Anyone have experience using pryocat hd with Efke IR820? Will this improve sharpness over using XTOL? Any development time recommendations? I'm assuming standard pyrocat development temp of 70 deg F.
Cheers,
John

Standard development temperature for pyrocat is 75, not 70. At 70 the time must be extended.
