I wear either Corrugate Guide or Obsidian from freezing up to about 70F, depending on how quiet I need to be. I'll be switching to the new Guide Lite pants above that this year - it gets above 100F in August where I hunt.
Neither are rain pants and DWR wears out with abrasion and time - I carry Marmot PreCip full zips or KUIU Yukons for "real" rain.
I only use Timberlines when the highs are below freezing - think late season NV muley. In conjunction with a 200g merino base layer, I've been down below 0F in those and been just fine. They're heavy and pretty decent at keeping the wet out, but not worth slogging around in if you don't have to. That said, my hunting partner runs cold and wears them in the mid-season (highs in the 50s). YMMV of course.
