Feiser, dominant for two years in the the 300 hurdles and now must also fill the shoes of the departed Beth Sprecher, won both the 100 and 300 hurdles.
Stouffer was her usual steady self, winning the 800 in 2 minutes, 31 seconds, and taking second in the 1,600 in bitterly cold and windy weather.
"In this wind, to have a 2:30 is amazing to me," Stouffer said.
The Leopards turned - as they always have - to their relays for much-needed points, winning the 800 and 1,600 relays. Smithsburg tacked on four more second-place finishes and five thirds to hold on.
"It's a great effort from all our kids," said Leopards coach Buddy Orndorff, who has always hinted at retirement but is back again. "Great day for our relay teams. We're still mixing and matching. ... We got great leadership from our seniors, and our youngsters are catching on."
North Hagerstown finished third with 90 points, while Williamsport was fourth with 63 points.
Melissa Wynn almost singlehandedly lifted South Hagerstown to sixth with 42 points, either directly or indirectly giving the Rebels 40 of those by winning the 100, 200, 400 and anchoring the winning 400 relay. It was a breathtaking display for the senior after missing the indoor season battling pneumonia.
"I'm trying to get over it, get out here and do what I do best," Wynn said. "Just winning, that's my biggest goal."
Sarah Harris carried Boonsboro to eighth place, scoring 28 of the Warriors' 35 points in winning the long jump and high jump and finishing second to Wynn in the 100.
- On the boys side, Patuxent ran away with the team title with 117 points, while Smithsburg turned two firsts (Corey Brown's triple jump title and the 400 relay title), five seconds, five thirds and two fifths into 94 points - good for second.
Brett Morrell and Daniel Robinson combined for 56 of Boonsboro's 81 points as the Warriors finished third. Morrell won the 300 hurdles and 400, while Robinson won the 110 hurdles.
Williamsport's Phil Taylor won the quadathlon, running to victory in the quad 800 to cement his title.
