I have both the Locus Gear and the Black Diamond UL Distance poles. The Lotus Gear's are slightly stiffer, but my version of the BD is older and I think the new ones are stiffer. I really like the lighter weight of the BD poles and never adjust poles on the trail, but like the adjustable poles for my shelter. (Before the LG poles I just added a rock or changed the angle of the pole to raise/lower).
In my opinion the Lotus Gear poles would be durable enough for a thru hike. That isn’t saying they won’t/can’t break if you fall on them wrong, but other than that you should be fine.
The downside is that if you do need a replacement section on trail, it will have to be shipped from Japan.
If you use poles for your shelter, get the Lotus Gear, if you don't save some money with the Black Diamonds.
I have no experience with the Ruta Locura poles and if I remember right they had weired grips.
