That's a tough weekend for me too. Homecoming at my high school and both of my colleges all on the same weekend. Choices would have to be made...
Stagger, they are very spooky. But a very different type of spooky. On Valley they kind of sulk, maybe slide just out of range. Give em 10 minutes and they start feeding again. On brookie streams if you spook them, maybe you see them dart, maybe not, and they're gone like they never existed. They may not come out again all day. Even days after a good spooking, the stream won't have fully recovered.
So spooking is much more severe. But I wouldn't say it's easier to spook them than on Valley. In fact, with heavier currents (lots of whitewater and such) often you can approach closer WITHOUT spooking them. But then you couple that with often HAVING to get closer just to make a cast.
Not nearly as picky, for sure. Patterns, drag, etc. Forget about it. If you locate a good stream, get yourself there, and it hasn't been fished that day, and it's not ridiculously low, you're going to catch fish, likely double digits, and 30+ isn't unusual at all.
