So the LA pole weighs roughly 1lb 12oz and the Drennan version 12oz, which means that the LA pole is 2.33 times the weight of the Drennan....and that doesn't matter to some apparently? In which case, why not swap ALL of your gear for unnecessarily heavy versions, until it weighs 2.33 times what it does now...after all, it doesn't matter, does it? Just because you have spent years paring your gear down to the bare essentials, to get it as light as possible for roving, doesn't mean it REALLY matters if it is suddenly 2.33 times heavier does it
The thing is, nobody has suggested that the Drennan pole is not strong enough, have they? It seems it's only fault is that the locking mechanism fails if it is abused. The logical answer to that apparently

rolleyes

is to buy one weighing more than twice as much...because it's stronger

Beats the hell out of giving a lovely light pole a couple of minutes of your precious time occasionally...which apparently is all that's needed to keep it in perfect working order for years on end
I personally use an old, VERY cheap telescopic match type landing net pole....because it's light, does all I want of it, and still works perfectly well. However, should it ever give up the ghost, I will have no problem in buying the Drennan to replace it. Being logical can be SO illogical at times....apparently
