I agree with Rick. I don't think you'll have any problems. I've camped at Duck Hole and nearby several times, with hung bags, and never had a bear problem. Similar in Dix Wilderness, never a problem.
In my opinion, the bear problem in the Marcy Dam/Flowed Lands corridor is the result of inadequate education and lax enforcement of good common sense practices like bear bag hangs. Now, a problem has been created because the bears are trained to look for camper food. I don't think the bear canister reg is going to solve any problems. (It's just going to be a damn asinine inconvenience for the majority of us, who are camped nowhere near Marcy Dam, never had a probnlem with bears, and don't need a damn stupid canister banging around on our backs.) Canisters won't solve the problem, because after an initial flurry of attention, we will go right back to no education and lax and selective enforcement, which are the real root causes. This is due to inadequate resource allocation from Albany. Again, someone in an office will be able to say they "did something about the bear problem" by passing a new reg; but it will not be enforced in the long term.
