Ask for invite to build a jib. Last summer we tried a lot of different things including animal birthing lube, AKA bovine butt lube. There are plenty of edits where turf is used successfully, but I never figured it out. There are different varieties of construction fence and some don't slide for shit. I suggest this stuff sold at Lowes or Home Depot for your drop in. It is pretty much fool proof.
It's great for drop in, but tough to grip on for spins onto rails, so for the actual jump, you want to use orange construction fence. Not as fast as the lattice, but you can grip better on it.
Otherwise you can wait a little until Luke and Adam have their new back yard jib product out.
