I have to say I have yet to run a PL VTR tire in truggy.
AKA CityBlocks/Ibeams and JConcepts Sevens keep me covered.
I have a set of PL VTR Calibers that I've yet to run.
If JC comes out with Truggy Subcultures, I may never run PL again. I've just about gotten away from them in buggy too; but sometimes M3 is just THE compound on some clay tracks.
