Four Comments:
1) you blew it by not ramming the seal at 1:05...really disappointed, in fact, almost stopped watching at that point...
2) those big arse arms were getting tired? See note in above comment...I'd want to arm wrestle you if I were just a bit younger...
3) So...how many damn GoPro batteries do you burn through in a trip? Way to hang tough all day!
4) Nice hard fight on a slug fish! Very good video!
