One very important factor when considering any jumps or features is how easy they are to both get out and put away. I agree that the ramps in the clip from 200sx's post are fantastic but they are on the large size and would need more than 1 or 2 people to move some of them.
Maybe if we all chipped in with design, building and making use of them then as a club, we could make best use of the facilities we have and some of the skills us lot have in our normal lives and bring them to the club with us.
