Re: deceiver patterns
The half and half is a great pattern that is a combo of the Deciever and the Clouser Minnow. its basically a clouser with the deciever tail on it. works best on size 2 and bigger. I often cheat when tying them and make the tail out of marabou, bucktail, or a synthetic since that's easier than matching up 6-10 saddle hackles. Craft fur works well on smaller ones, and pola-fibre or some of the EP stuff works great on bigger ones.
One other clouser tip- don't use lead eyes. Lead is quite heavy, but its also fairly weak. It's very easy to smack the fly on a rock/dock/etc and knock the eyes off totally. I like the hourglass brass eyes that are tougher and I think easier to tie in as well.
