There were so many PK frames churned out under just as many different model names during the 80s and 90s. It's hard to summon any enthusiasm for their frames beyond their most recognised ones.
If I pickup a Kennex on my thrift store travels, it's usually one that is roughly similar to the Black Ace 86 or indeed the rest of the early 80s Ace range - i.e headlight thin beamed (17-19mm) midsize frames. I pass on everything else - with the exception of the dark grey Graphite Destiny - my personal "white whale" - never found one of those yet in all my time thrifting.
I would suggest picking up whatever PK frame best matches your ideal playing specs and just ignore the model name.
