Your posts are a little scattery haha.
Choosing a board length has many factors.
Weight, Height, size of boots, what style of riding you do, and also what you personally like to ride.
So maybe a 159 in a certain board would be great depending on what you want to do or maybe a 162 is right for you.
To answer your question about camber.
Regular camber boards are like an unhappy face.
Reverse camber boards are like a happy face.
There are a lot of styles of reverse camber boards.
Things like how much of the board is reversed and where the reverse camber happens.
There are also boards that are camber and reverse camber.
I own a Arbor Westmark.
It is 2 years old now i think. It is a midwide directional twin.
I rode it for a while but just could never get with that directional twin stuff.
It was probably all in my head but something about it felt weird when riding switch.
For the most part Arbors have a great reputation and i think they look pretty awesome.
If you want more help with what boards might be good for you try listing some of the things i posted above.
