I know you do, but equally, you don't like 15'+ rods (for any purpose). I also know that you use a wading net with a longer handle that I'm remotely comfortable using. My wading net of choice is only fractionally longer than a traditional trout scoop net. I'm not comfortable using a rod longer than 13', but I make an exception for a single 13'6" rod. 14'ers are a step too far for my liking with the nets I choose to use when wading. There's absolutely zero chance of me using a 15'+ rod when wading.
It all boils down to personal preference. There's no right or wrong.
I find 12' rods pointless because I'd rather use 11 or 13' in every scenario I can think of.
Likewise, I find 14' pointless because I'd sooner use 13' or 15' in any angling scenario I expect to encounter.
I don't want anyone else to do the same, they are quite free to do whatever they want. I'm sure that for some folks, 12 and 14' rods will be their ideal float rod lengths. I do know I'm greatly relieved that I've little use for 12 and 14' rods. I've little enough storage room as it is!
