I’ve done well for shallows in CA with slumpbusters and meat whistle flies. Finding the right retrieve is important, depending on their mood and water temp.
I use both the Veevus GSP and Semperfli Nano silk. Both are good and even the small size 50d will work well for spinning hair. I prefer the nanosilk, have had several spools of Veevus where the thread separates and somehow gets trapped int he spool, basically ruining it.
