Hi Matt
You raise a topic that has been brought up several times among my fishing mates - usually around a bbq or fire.
Firstly (obviously) it's a personal choice and depends where it sits on your priorities.
From a personal perspective ..... After seeing many mounts over the years - I've seen very few examples of large fish that do it justice - the best seem to be smaller fish like small barra and trout in a lifelike situation - the flat ones that go on the wall - Nah .
A lot of guys said that they wouldn't do it again ....... because they caught larger or more significant captures later ..... or they just regret it
I think your world record made for a compelling case - but did you know at the time it would be ratified....... it was a significant capture regardless .
$1000-1500 is a lot of money for a dust collector
I'm more for a really good photo ...... its why I spent a considerable amount on an digital SLR & now the go -pro. A high resolution photo that can be blown up and framed ...... The only thing is having someone to take the photos and do a good job of it - Though I would review the photos ...... my PBs photos are crap because the photographer didn't really give a hoot and was a poor photographer ...... yet OBI_WAN did a great job on my number 2.
Finally ..... I did get that warm & fuzzy feeling letting those big fish go

- who knows those big fish could also be someone else's fish of a life time
I hope you get the chance to make that decision
Chris
