I'm just curious to see if I can develop a feel for how it goes. This kind of modding is so rampant at the Discord these days. As for your arguments:
• Swapping 2 more keys at this point, and even having them change hands, doesn't matter much. This topic is about doing just those things, for a possible minor benefit.
• Moving V is something I've been concerned about a lot since you made the DH mod in 2014, as you know. At first I tried to avoid splitting up ZXCV but eventually I gave that up. Now, this creates trouble for me using Extend since I decided to keep the Extend-Paste mapping on the V key which causes more work for me as I then have to implement Extend both with and without the D-V (B-V) swap. Now with the V-K swap, V goes all the way to the other hand and I'm trying to keep the Extend-Paste mapping next to Extend-Copy again. This is every bit as annoying for me as the letter swap itself right now! But maybe I'll end up using it. I just felt it'd be too strange with the Extend-Paste and V itself on neighboring keys, and now that's no issue anymore.
• I'm not enjoying it so far. The KN bigram used to flow so nicely with alt-fingering, it's worse now. Heh. Overall, it feels awkward. But I know those are beginner misgivings.
[Update: Ditched it. The swap fixes two problems I didn't have since I alt-finger (NK and LK), and causes trouble with CK and VE bigrams – possibly others too. These aren't SFBs nor weak-finger near-finger-bigrams, so the Colemakmods analyzer doesn't pick up on them. But they felt awkward just the same. This swap isn't as beneficial as it first appeared to the naïve observer (me).]
