Sprung 5 is a must watch, its slightly old school now (early 00’s maybe), but has some excellent riding and camera shots and puts some of the newer movies to shame i think.
NWD 10 is my fav recent one.
All the Earthed films are pretty good as well.
You can download them all for free at Extreme-vidz.com.
NWD 1 is a must see i think for the opening Josh Bender segment!
