Your English politicians are just like they are from the magazine Mad. No future plans, no vision at all, but those zombies just repeated BR exit BR exit BR exit. You normal Brits can't help it. Trade and good contacts will survive, why not? Europe sucks, but no European community sucks even more. We will let the poor countries drop dead, won't we? We prefer a selfish Europe. All countries must ignore they do need foreign markets. We should hate all the other countries. We are stupid. Shortsighted. That's why Brexit is possible. But again, you can't help it. Your politicians are to blame. If you don't like those power games (France vs Germany vs UK is classic), you could fight that stupid power game. Try diplomacy, try to emphasis our mutual interests. Those exist! Giving up on Europe is completely understandable, but still, it is too easy. Things will grow worse without the UK in Bruxelles! Don't you agree? Now get your boom sorted. Who needs this boom video anyway? Off coarse you set your boom right. Or you will suffer.

I am not super familiar with Naish but generally, top hole gives more power whilst bottom hole gives more control!

When waveriding your boom should be about your chest height, because you want to get low on a bottom turn. But if you want to freeride or do anything else you should put it more about at your shoulder height. Your height doesn't matter as a reference point.

Well of course too much of everything makes no good. When waveriding you should put it at your chest height to allow yourself to put the sail lower for a bottomturn. Freeride or freestyle probably higher around your shoulders so you can get planing more easily.

Should a person get an aluminium or carbon tree?

But the Dutch don't call it boom, they call it giek.
