Believe me, I've seen it change in just the 15 years that I've been fishing TR. To catch them shallow consistently, you have to love fishing that way enough to grind and grind and grind some days. Even then, it takes some tricks up your sleeve and years of trial-and-error that not everyone has. Sprint21 and a couple of others around here know the deal.
And then some days you just have to get out there with the Bo's, Bablers and Becks of the world and hope they'll scoot over and let you in on some of the deep fish.
