I think it's been said - There is not much gear snobbery over here, you make out that the US has a lot of it. You also make out other things that other US cavers flatly refute, so I'll take it with a pinch of salt.
Over here - If it works, it works.
I think most experienced cavers can cast an eye over something and get an inkling about it being suitable or otherwise. If you have a truly novel piece of kit, like the Turbochest when it first came out, you'll get lots of questions. Not snobbery, not "that won't work", but genuine, interested questions. I still get the odd question about the Turbofoot - I'm the only person I know using it, most people haven't seen one before. I've yet to encounter anyone telling me I should stick to a Pantin.
