Your idea of using another neg w/ a good sky to go w/ your current neg is an old established idea. Sounds good to me. Years ago I read about a photographer from 100 years ago or so that did the same thing religiously, and several of his really good prints all have the same skies. I always use D76 full strength. It's confusing looking at the directions for developing on the box because they list 4 different types of Tri-X on there! At any rate, I normally go w/ 7 minutes at 70 degrees w/ full strength in D76. Don't use this as your development times though, as I am sure your agitation scheme and local water is totally different than mine, but it's as good a place as any to start. I'm not getting much extra contrast on my negs, assuming the times I have standardized are kept consistent and assuming I exposed it properly. This is all for 35mm. For 120 I tend to give it a little extra time in the developer to punch up the contrast a little. You can get away w/ that w/ 120 because t looks so smooth anyway, compared to 35mm.
One issue I have w/ D76 is that after a few weeks at room temp I start to get problems. Sometimes it's weaker, other times it seems to cycle up and give more contrast. So if it's anything important I mix up a fresh batch, let it set overnight, and get perfect negs every time.
