They all looked very nice.* I'm sure the fish will like them.
For baetis, there are three major stages that are available to trout-
nymph: weighted or not (pheasant tail or other mayfly nymph patterns)
emerger: weighted or not (barr's emerger, rs2, etc)
surface: dry flies and stillborn (adams, olives and criples)
This insect is usually around size 22-20 in Colorado and can go from size 26 to 18.
Also, there are plenty of variations of the above patterns.* If you do a search online, you will find plenty of patterns.
Hope that helps.
