Hobie livewell xl

Hello everyone,
I have just recently (within the last year) Gotten my hobie pa14. Before kayak fishing I fished bass tournaments out of my big boat, and would like to continue to fish tournaments every so often. I'm now stuck on the dilemma of keeping the fish alive, both for weigh in and for putting in my personal pond every so often. My question is has anyone tried the hobie livewell xl for larger fish besides bait to keep them alive, and how did it work. Also what kind of run time are you all getting out of the livewell.
