Trolling a mack

[ccacher1]

Is there a trick to not killing your mack 5 minutes into trolling it? I went out last weekend and blew through my bait because they kept dying on me or becoming very lifeless. I started thinking about it afterwards and thought maybe it was because I was hooking them from under their chin up through the nose, thus forcing their mouth shut so water can't flow through it and through the gills. Maybe cross hooking their nose is a better call? Any tips would be greatly appreciated, thanks.
