Kind of a hit/miss. Usually on 1/16 oz and 1/8 oz I use a #3 as these are in first pic. I have found the inline blades to be the best, sometimes the willow blades are hard to get them to spin unless the wire is perfectly straight. I use both gold and silver usually on the same lure color. Typically using the Gold on cloudy days and the Silver when the sun is out. I catch the trout here on both dressed and non dressed trebles. Although I think the lure over all looks much better with it dressed.
