Whats Easier to Learn? Russian or Arabic?

I want to either learn Russian or Arabic. Which is easier for me to learn? And which one is more useful in the world.

I currently speak French, Spanish, Portuguese, and English

How do you say "smooth, easy writing" in chinese, french, spanish, arabic, russian, hindu, and german?

And if anyone knows of fonts that can be downloaded, of these languages that would be great!

I'm trying to make some promotional advertising for a marketing class and need some other languages incorporated into my presentation

... if/ when he moves to another high school. The other high school does not offer Russian as a language. Choices are German, French Spanish, Latin. Which language would make an easier switch for a kid who has enjoyed/excelled in Russian? I'm thinking French or German? He does not have a preference, just wishes he could continue Russian. Three years of one language are required for a college-bound high school diploma in our area.

I'm very interested in learning Russian but because I don't have a formal teacher I would know where to start. My school only offers French Spanish and Japanese taking French not my choice. Are there any beginner guides I can use so that I will know how long I should spend on a topic.
