Very cool article ... thanks for the link!
In our area in the early Springtime, larger brown trout can often be caught at night by stripping a Deer Hair Mouse across the current in a pool. As the season progresses, they'll move to smaller surface flies instead of larger meals. Right now, they won't look at a fly any larger than a #16, such as small Caddis imitations, Queen of the Waters, or Dark Cahill's. Brook Trout and 'Bows tend to be less selective.
It's now Atlantic Salmon season in these parts, but the early reports aren't very good.
