I don't think I've ever not had at least some success with soft hackles. Not always the most effective fly on a given day, but usually can depend on catching a few on 'em. That goes for most species I fish for, and I fish for most species-- from trout to carp. I tie them small and sparse for both trout and panfish, big and heavier hackled (maybe two full turns of hackle, not enough to inhibit motion and up to size 6)for bass. The one you have pictured looks great. Pheasant tail and peacock herl make good bodies as well as the traditional floss in various colors.
