Steve,
I went into Outdoor Emporium today. It's a great place - only 12 blocks from my office in downtown Seattle and a pretty good bass selection. The people there were really nice and also told me that they will be expanding their bass selection over the next few months.
On the 176's, I have to respectfully disagree...
Yamamoto makes the 4" and 5" Senkos in 176. Auburn and Sportco both carry them. I'm not sure about the 6".
