Yeah, it's the Hunter one I see as more of an issue. The PM6, from this angle at least, looks okay. I think the recessed round connector on the Hunter is to fit their cable which you can see in that PM6 pic, but my issue with that is what if you use a 2-pin cable not from Trinity? That's the point of going standard 2-pin in the first place, right? Not everything is going to fit in that hole and even if they did, they're most likely rectangular and now you've got just a ton of empty space for dust and oils and other crap to accumulate right at the connection point. Poor design choice IMO.
To be honest, the hunter and PM6 were supposed to take the modular cable shift they did with the master and icarus, so the "trinity" 2 pin is due to the community's reaction to the modular cable. Considering the type of cables which are supposed to come with the PM6 and Hunters, why any other cable be necessary? Seems like it's a non-issue to me.
