I wonder what fingers you have been using for which keys?
If you've been using your index finger for C and middle finger for X, then you have adopted the recommended "angle" technique but are using the wrong fingers (sometimes called the "angle cheat" method).
Yep that is what I have been doing.

Or, you might have been using the traditional technique (C with middle finger), which is the correct finger assignment but is significantly less comfortable to use.
Using the Angle Mod gives you the best of both worlds: correct finger assignment plus more comfortable.
]]>You've been using the DH mod without its included Angle mod. This variant is intended for matrix/orthogonal boards. Row-staggered boards such as ANSI have a severe weakness in their traditional fingering technique in that the right wrist can be kept horizontally straight but the left wrist can't – it experiences what in medical terms is known as ulnar deviation. This is strainful and bad for you, so the Colemak-DH layout includes an Angle mod.
For QWERTY it doesn't matter so much since the whole layout is so bad, but Colemak was developed for the traditional technique in which for instance EDC (Colemak FSC) are all on the middle finger. Some QWERTY typists simply "Angle cheat" for a straighter wrist, typing C with their index finger. Again, that doesn't matter much on QWERTY but on Colemak it's a bad idea as it ruins some of Colemak's excellent design benefits.
