Well I ordered some of the Tiburon pants. We'll see how I like them! Thanks for all the help guys.. even though I didn't go with any of the alternate decisions.
I thin you'll be happy with them for your stated purpose. Mine have held up pretty well to 2 years of wear, they are pretty fuzzed up, but only have one hole where they got caught on some old barbed wire hiding amongst some vines.
I will likely replace these next year and am looking at some offerings from arcteryx that are about $40 cheaper. I'll give up the hip vents which is a bummer, I think any serious hiking pant should include them at this point, but will gain an integrated belt.
I have tiburons, Sitka ascent, skre Unitas, Eddie Bauer guides, and tiburons are my go to for hot and humid conditions. The Unitas are good too. I'm happy with either one.
