There are also some quite nice non-home row ones:
- "ft" e.g. in often
- "un" e.g. in stun or tuna

If you are using my DH mod, then I'd add "the" and "nds" are lovely trigrams!

D and V are both left index.

With the left hand attacking the keyboard angle-mod style, the index finger naturally slides down from the home key (T) to the key left-and-below of T (i.e, the Qwerty C key). So, my argument is that this key is much superior to the V key and deserves a frequent letter, hence the D. This makes words which end -DS excellent to type. In fact typing DS is almost the same as TS.

In other words, to me, the best keys are the ones highlighted in red:

As I am the OP and this is the Experiences section, I'll tell a little about my experience with Colemak and Mods.
I started with original vanilla Colemak and added Colemak layout as input language in Windows. Then I discovered PKL and found out that it is much more convenient to use it than to install new input language in each new computer. I'm also using rulemak and it is easier to do that via PKL. Remote desktop works good as well, just need to run PKL on both computers.
Then, DreymaR convinced me to try Angle-Wide mod, and that finally reconcile me with the standard staggered keyboard. I'm using ANSI keyboard, it is hard to find ISO  keyboard in US, honestly in 15 years I haven't seen a single one. But even moving Z and / inward is not a big deal, they are used quite rare and I did not have problems with learning their new position. What is good about Angle-Wide at ANSI keyboard is the symmetrical and easy to access position of Shifts.
I also have ortholinear keyboards at home (Ergodox and Planck) and using them sometimes, although not so often as the standard ones.  These ortholinear keyboards use the standard position of Z, /, and ', and I'm switching easily from Angle(Z)Wide to regular and back.
Regarding DH mods. I never felt the need to use them as I'm quite comfortable with the original DH position, but I definitely see the point typing "the" and "he" (and "ing") all day long. While "he" and "ing" are my fastest grams and "h" is a fastest key. :)
I might be ready to try DH mod now and my choice will be the Steve's DH mod just because of its optimization for ortholinear keyboards. I'm still planning to use to use Ergodox as my daily driver in future. Without staggering, D in place of V and H in place of M looks much better then D in place of B and H in place of K.

Thank you DreymaR! I appresiate your contribution, you are the soul of this forum.

Glad to hear about your positive experience, ckofy!

The M is the only key I had slight misgivings about, but is easily outweighed by having the H in the far superior position. So many bigrams/trigrams are improved, as you have found! You are right about "ing", even though the G is in the central column, it's somehow is easier to access it when the previous key was on the other side, making "ing" quite comfortable. M and G have similar frequencies (around 2-3%), which is about right for centre column keys. I found B being on the top row took a while to get used to, but it certainly beats having it in the default (non-angle-mod) position!
