I must admit, Chum do seem to be pretty impressive.
Thanks to some good advice on this forum I got my first one, actually my one and only, Chum salmon on a fly last year and it was murder getting it in - not even a fresh Chrome one either. The fight went a lot like that tiger fight I posted - below the surface all the time and lots of power.
It was about 12 lbs so it's hard to compare with the smaller fish I normally catch - there was also a pretty strong current to contend with. I would say a carp of the same size with the right temperature conditions could be just as impressive but I have never caught a carp that size or under strong current conditions.
