What is it about competitive hobbies and having the best kit. If you go fishing and have the best rod, bait, hooks, where's the upside? You cant be sure that massive fish you caught is your skill or just tech. Everyone would expect you to catch a big fish because you have all the kit.
If on the other hand you just have a cheap rod etc, that big fish you catch, you caught because of your skill. The guy sitting next to you with all the kit, that's just caught a massive fish is ok, because he has all the kit.
I've noticed the same thing with cycling and golf.
I suppose you could say its to prove you're part of a group, but isn't being sat in the rain, next to a muddy pond proof enough?
