Depends....sometimes 1/4 ounce....sometimes more....MUCH MORE! Yesterday I was flipping and punching with two 1 1/2ounce tungstens pegged. The mat was an inch thick and I swear a raccoon could have walked across it no problem. A few times I had to flip up high and snatch down on the rod to blast the 3 ounce weight though to the bottom. Must have been crazy looking to a fish. Probably looked like a meteor shower under the mat!!!! Haha. But...hey....we do what we gotta do to get to the fish. And it worked.
