Early AM in the fog would be prime for the fly....that's just what's brother did he same morning I got the hybrids. My challenge is usually a 2 hour window, and extremely boat and wade shy fish in shallow water. Most of my strikes and blowups are on 200 ft casts, and every time I get the canoe near the breaking fish, they spook. With the stealth of low light, you could make it happen. Jay landed about 8 fish and snapped his 7wt on one.
These schooling hybrids range from 5 all the way up to 20 lbs and they're cruising in 4ft of water.
