Regarding the PLS (strictly baseline)...
I have various ranging from FR-1.20. The mold pieces are extremely consistent: Cheetah top, Whippet bottom, no noticeable spacers. PLH tends to vary with materials used. I find early runs (pre CE) have higher PLH on average & wear faster. The CE run, 1.13, is consistently the flattest; they maintain their sweet-spot the longest IMO. Post CE runs are somewhere in between on both PLH & wear, again material dependent. Personally, I bag 1.15, 1.13, & FR.
