I see you also have been misinformed. The ability for a container, eg bladder, to hold to a higher pressure has no relation to it's diameter.
Just need to correct this - NorCalNomad is not completely wrong on this, but the statement is misleading.
What do you mean by "misleading"? This is not political/social studies where there is no wrong answers. In hard sciences you are wrong or you are right. Completely.
To put it in the layman terms, and in the content of the prior one pump discussion, if one can safely pump the LE to 6 psi, and kite struts are twice as thin, they can be safely pumped to 12 psi (which is impossible to achieve with one pump system). As you pointed out, this is law of physics, so it has all kind of applications beyond kitesurfing. For example, thinner 22mm bicycle race tubes are advised to be pumped to 100 psi, while 28 mm road tires to only 50.
Now, let's again analyse the "latest and greatest" North innovation of increasing the hose diameter. It is moronic at least for two reasons:
1. Higher diameter means increased weight.
2. Higher diameter tubes can withstand less pressure, so you need to reinforce them by making thicker, increasing the weight even more!
Again, I have nothing against one specific company. This is just one more exhibit to add to the official thread of pointless innovations
