That's a monster halibut. And great advertising for Penn.
"Buscher used 50-pound test braided line and a Penn Torque 10 reel mounted to a 7-foot Penn Torque rod"
That's actually a very small reel for that big a fish. I'm sure they meant the 100 model, not the 10. There is no 10 and the 100 is the smallest of the Torque series reels. Looks like I may have found a new grouper reel.
