With a DT you don't want to 'over line,' especially with a light rod as you've described above. Remember the 'line weight' is just the first 30 feet. As you pull out another 10 feet (just for numbers) you now have one line weight higher out the rod tip.
Using the 5wt numbers as an example, that's a touch short of 5 grains per foot (lets ignore the front tapered portion to keep this simple). Using my example of an extra 10 feet that's close to an additional 50 grains, or one third the weight of the first 30 feet. Or to put it another way, that '5' at 40' now ways far more than the 6 at 30 feet.
