I'm and intermediate rider and I can do almost everything with 180s out on boxes and flat rails, but I've taken some pretty bad slams doing 50-50s and FS/BS boardslides on downrails for some reason.. Any inside advice from jib masters here?
I just replied this to another thread. Copy and paste...
Start by just ollieing next to the feature without hitting the rail. This will give you an idea of how much you need to pop to get onto the rail.
The big thing is just committing. Once you work out how much to pop, come in parallel to the line of the rail (frontside is easier to start with), come in on a slight angle as you approach and pop as you practiced next to the rail. This time you're going to focus on the rail, making sure you get your board on the top of it. Stay balanced and centered and look straight down to the end of the rail. This should keep you locked in. Ride off and spot your landing.
I'm getting to this point. The guys that I have entrusted with my park tutelage say to practice "ollie'ing" over the feature. You will need enough pop to clear the rail and land on the other side. This will give you the confidence that you can ollie onto it. The next step is to then ollie onto it, knowing it is a rail that you can clear, now just pop a little less and land it 50/50.
I have practiced this in the basement and hoping to put it into actual practice as soon as our park is set up.
