Thanks guys, i'll probably try the flatbar because it's in the hike park, the only slim tube is a single barrel handrail that's on a down slope. Regardless, (hopefully) i'll have my first and second rails. That smooth tube has been haunting my dreams.
Other questions: where should my hands be? how much should i bend my knees? should i pop off the end or just ride it off? when i afterbang, how much should my head weigh?
all help much appreciated
