Mercer's Tungsten Skwala
The Mercer Tungsten Skwala represents the Skwala stoneflies that hatch in early spring. If you're heading to Washington's Yakima River in March or April, you'll definitely want to have a handful of these in your box. After a long, cold winter the trout can be pretty excited about a big meal floating downstream and the Skwala hatch can be some of the best fishing of the year.
