pmk and rollo pyro with hp5+ and delta 100

I will be using BTZS tubes to develop 8x10 HP5+ and 4x5 delta 100 and possibly 4x5 delta 400. Need starting times for PMK and the newer version rollo pyro. Ihave a densitomer, but it cannot read the pyro through the pyro stain. I have tested via darkroom innovations, but my times for a "normal" negative would be less than 4 minutes. The dilution I used was the recommended 2:4:100 for the rollo pyro. Would appreciate any info especially if anyone has used the rollo pyro at a dilution of 1:2:100. I also think I can get away with using just plain old PMK in the tubes since I hear it doesn't oxidize as much as fast rotary systems. I dont mind testing, but I'd rather be out shooting and fine tuning. Thanks.
