That's interesting Scott...I have caught large RES on mini BG cranks too, and jig/crawler on bottom works well for me, but that's about it in my experience. I think nymphing with the flyrod would be a challenge - but may also be productive once one learned how they preferred the presentation and found a good pattern. I will pay a ransom for anyone who can get a photo of a RES taken on the flyrod - cocktail of the angler's choice at PB VI.
