3366 is an excellent hook for Clouser Deep Minnows, foam bugs, deer hair bugs, Blonde-style bucktails, and about a million (maybe more) other patterns. An extremely versatile hook at a good price. Not everything needs to be tied on a boutique priced jewelry store hook, and these work great. There is also a 3366A, which has an oversize eye. I use those for tying flies to put behind spinners.
Feather Craft is insanely overpriced at $4.95 per 50. The last several hundred I bought were from Jann's Netcraft. $4.18 per 100, up to size 1, then slightly more.
