I'm pretty new to the stillwater fishing game. On the first week of April, we're going to be headed out on a tour of various E. WA lakes for my vacation/kids spring break. I'll have the 12' boat and float tube and I have a lot of spots earmarked to check out. What would be some good and somewhat easy to tie flies that might be productive for these fisheries? I'm just looking for some "good to have in the box" type of offerings to add to my arsenal for this type of fishing. I'll mostly be fishing the basin lakes.
