Here's something else to consider: forget the hook and focus on the float. A good float will show you bites much better than a poor one. I use very small hooks (usually #14 and #16 fly hooks) and RARELY deep hook a fish.

Try some of the Thill Shybite, Mini-Shybite, and Mini-Stealth floats and add enough shot so that just 1/4" of the tip shows.
