Hi everyone,
I'm currently in the market for a dolly or slider to film action sports and other video related pieces. I've been thinking of getting the Welcome To Eazy Dolly.com (http://eazydolly.com/eazydolly.html). It was made by someone who films skateboarding and seems like the best choice.

However, would a slider be a better choice as its more portable? Or would it be to slow to film a moving biker or snowboarder?

Thanks,

Wendell Frink
