Lots, simple and cheap early. Wooly buggers are quick and simple, chartreuse, oranges, red, blue, black, pink, white. Even wooly worms, but the maribou in the bugger may draw more takes. A size 6 nymph hook 2x has been the best all around size, but havjng a few larger and smaller in the main colors is a good idea. These are a lot quicker to tie than the bunnys, so it won't hurt as much when you hang them up, and you will lose tackle. As the season progresses, more things come into play, but you will still find the buggers to be a reliable fly, and if you end up the season with leftovers, you can troll for brookies in the 'daks, or use them for smallmouth fishing.
