What Preston and Curt said. They are amongst those at the top of the searun cutthroat game (as well as DCSmartie), and you can't do much better than following their advice.
Clousers work..I like olive over white, with a little flash and some red just behind the eyes to simulate gills. I'm leaning away from using these, as they are a beotch to cast compared to unweigted or less weighted patterns. And, I cringe in agony when I hear those dumbell eyes strike my graphite 6 wt.
For estuaries and lower reaches of rivers, and frog water, I prefer an orange-bodied Reversed Spider, with mallard flank (what I use, since I have alot of it) hackle and a tail of red hackle fibers. I vary the hackle shade from (dyed) lemon yellow, wood duck, and natural. I like 'em in size 6, but use #8's as well. Sometimes I use a yellow body (with red tail).
Sometimes black body. I just bought a Lady Amherst Pheasant head for the hackles for the black ones. The hackle fibers don't stick together like mallard flank will.
Hope this helps.
