Suitable fonts

I've decided to use a sans serif font. I think it would be more effective and would look a bit more boyish than using a serif font. I also think that if i used all uppercase letters it would be clear to read. I looked on the website Dafont to see if i could find some appropriate fonts.

These three i think would be very suitable. "Freeroad" would have a good impact but "Code" would read better. I like "Boarder" because its slightly edgier and would be playful and interesting for the boys to look at.
