Thanks for all your suggestions...so much to consider, but what I have taken from them all is that, and as usual, trial and error and your ears are the only way to know what you like. After all these years, you would think that I would have used hypers before! It all turned out better than I expected, with me discovering a different set of nuances and directionality that the hypers provide.
Saying that, the venue situation was completely different than I anticipated. For one, the show was sold out to the point they were turning people away. 'Twas a sweaty mess by the end. There were no tables, so I was forced to set up toward the side. In addition, the basses were run thru subs that are built-in to the bottom of the stage, and the vocals and some stage mics were thru the PA's, so on-stage/stage lip would have been a mess. I ran the hypers DINa, and turned the mics more or less at the PAs and raised them so they would be slighlty lower than the PAs. In my reasoning, the venue was small and loud enough, that I would still get some stage sound in the mix. After a few minutes I realized that a 4-channel mix would never cut it, and if I ran omnis I would have more spilly-talking howling butt-nuts than music.
So I ran 4-channels in then end and basically did a comparison between the CK1x's and the ck63's. I found that there was a wider image with the CK1x's NOS and the mids were a bit richer, but I ran into some issues with the snare drum for the opening act, and ended up getting some phasing/reflection(?) where it sound like an echo. The hypers held their own, and I have a pretty tight stereo image, with the chatty crowd noise tamed back, and clear PA presence. Not too frickin' bad IMO for a bar gig.
Anyway, in the end, and after a bit of post-processing, my ears are happy. I am sure the bands are going to be satisfied as well. The hypers did their job, and I look foreward to doing some more experimenting.
As far the 4-channel mixing, most of you have mentioned the necessity of mixing up locations, spacing and polar patterns, and I can't agree more. I often use a quasi-Faulkner array for jazz gigs with an omni split with fantastic results. I am sure the hypers in the mix will be nice and tasty as well.
Should be a kickown for one of the sets soon...
BTW, I wanted to share something with you that you may find funny- just before Elephant Stone started the set he was tuning his sitar and I heard this atypical, non-jamband, local yokel, french Quebecois quote of the evening - "c'est une banjo ca?". Give me strength...a banjo? Yah, he's playing a banjo buddy...LOL
