Coot, I don't use the micros. The smallest I use is 1/16 oz. jigs for steelhead. In fact, I use 1/8. oz more often in low clear water than the 1/16 because it gets down quicker in riffles where the summer runs often hang out. I don't think the 1/8th size spooks steelies in gin clear water. However, the 1/16 has a little more lively action in times of low water flows. So maybe I am missing out by not using the really small micros? ...

As for a float in those conditions, I use a small 1" diameter round plain cork. It casts well, is naturally stealthy, and remains upright on it's own. You just have to be a little more aware of light bites when they occur.
