Hey, any of you have or have tried any of the Nitto handlebars? I'm considering them but have some questions. Feel free to answer all or any of the questions!

1) Is there anything special that they're Nitto?
2) Which of them are the most comfortable?
3) How do you know what size is for you?
4) What do all the specs mean and how do they translate to my size? What is flare? What is ramp? I think "drop" means the distance between the front and the part where your hands would be in the drops?

Anything else I need to know?
