As an old skool Carp duffer, I would say the lad had great sport! However I can't see the justice in playing a Carp of 10lbs for 20 mins.
So what have I leant, well nothing! But it just goes to show you need the tools for the job! IMHO a 1.5 tc rod and 8lbs bs Line would be better, also a carp friendly net and a mat would be nice too!
Having said that, the young man was in awe of his first Carp, that takes me back a few decades, and he looked after the fish too, which is admirable, OK not in the right way with all the gear we have, but he did it, and I enjoyed it!:w
