Using 16m on my favourite club lake would see me fishing the far bank, that is the one on the other side of the island.
Luckily I find no need to fish at more than 11.5m most of the time. Were I regularly being beaten by others fishing over that distance then I would too. And I would consider buying a new, better pole to do it with. But if I have no need to fish that long I don't see the point other than being able to say "Because I can".
I read of others who say that to compete on their waters you have to fish at 13, 14.5 or 16m. I obviously fish much different venues. Most of the big weights I see and have caught myself have come from much closer in. My biggest match weight came through fishing topkit in the margins for the first three hours then +1 for the second half of the match.
Fish long if you have to, but do you have to? Have you actually tried plundering the line that everyone else is ignoring and bridging over? Might work, might not. But unless you try you will never know.
