Hi wetnet - Have you seen this article by Loren Williams?

I really like the Knapek hooks, but they're awfully pricey. I'm working on getting a local supplier (Charlie Martini) to buy them direct from Jan Siman, but it hasn't happened yet.
The Partridge Flashpoints are nice, but tough to find. The competition guys gobble up the supply pretty quick. Every year, I whine to Jeff Pierce of Mustad, and he says that if there was more demand for them, there would be more around. Go figure... :-(
