simple dude....fish the big slow flast and tailouts and target the bigger fish poppin...take some practice distinguishing wich are tiddlers and wich are gooders but ur probably fishing the right fly jsut not fishing over the right fish...2-4 foot flats are great for a fish too feed in the evening they ahd some deepish water too hide and tehres not a strong current and its easy too look at whats drifting above...fish are a little more spooky tho in teh flats but thats were i find the bigguns...goodluck dude
