Unfortunately I haven't found a good retailer for beads in WA. I usually stock up in the summer at Mountain View Sports and Black Elk beads in Anchorage, AK. I would be willing to bet either place would ship some to ya. You can find generic beads at most craft stores and paint them yourself which is a fine option as well.

The secret weapon is the 12mil faceted in orange or red, add a little white or orange nail polish for a mottled look.

The thing I like about the weight above the first bead is that you are fishing two different parts of the water column. I like the bead rolling on the bottom, and the dropper to ride a little higher. Each cast is a little different with regard to how your gear gets pushed around, and sometimes each part of your rig is a little too one way over the other. By keeping one low and one high I feel like I am at least creating the chance for one to be right on the money.

Cheers.
