Yes.

Yes.

One could debate that.  Where I'm at currently is that the 30% dark-light is near optimal for crossovers, and I think 2 LKs is better than a strictly serial partitioning -- that is all different densities. Although the strictly serial, different-density approach profiles easier in QTR. You may have seen that I went to an LLK, 2 LKs and a K in one of the 1100 setups, and with the dyes I use 2 LKs and 2 Ks.  That is in a 1.5 pl printer (1400).  That arrangement is not just for ease of mixing and maintenance, but also because more than one experiment has resulted in double LKs as resulting in smoother prints -- less likely to band.  So, bottom line, what is "optimal" is very much open to debate.

The additional smoothness of the double LKs comes from more overlaps in the middle.  If you had the UT-C and LC (and K) in a separately partitioned channel so that they overlapped the LLK-LK-PK-K, etc. channel, you'd probably get more smoothness.  More inks firing and staggered crossovers are factors.

Good luck with the setup.
