Tips for adjusting fly fishing tactics from rocky mountain streams?

I grew up in Michigan but have lived my entire adult life in CO, and at the end of May I'm moving back to soend more time with my parents. I've spent a little bit of time fishing Michigan rivers and they are TOUGH. Out here I can easily put 20+ fish in the net on a decent day, and when fishing in MI a 5 fish day was really exceptional. I'm sure there are some population differences, but for me the toughest adjustment was the structure type. Out here you get really obvious breaks in flow to target, there are so many spots where that perfect speed of water exists from the surface to the bottom... but in Michigan there's always a smooth 3 feet of fast moving water up above the obvious pools, and no big rocks in the pools to target as obvious holding water... there are just less good seams of slow water to get good drifts in. Its a lot tougher to get a nymph down near the bottom, and the surface water moves so much quicker that finding risers seemed much less frequent.

I'd love any tips for rigs to use and structures to keep an eye out for to know I'm getting my fly in front of a fish with a good drift. The sandy bottomed streams are just so different from what I've gotten used to fishing. It seemed like most of my luck came from fishing very deep water, whereas out here I catch most of my fish in 2-3 feet of water around the edges of pools and runs, and a lot of the biggest ones actually come from even shallower pockets around a foot deep.

I'd also be interested in any tips on flies to tie up while I'm waiting to move. When I was fishing MI streams I had most of my luck trying to dead drift olive streamers, egg flies, and squirmy worms, all heavily weighted. It'd be fun to be able to fish some lighter dry dropper rigs though and not just be chucking and ducking a super heavy rig under an indicator.
