70 feet. Sounds like a lot of fun. You could send grapes across the room to someone. Making those beams solid is a good idea, especially the Bumper Beam because it will take a lot of abuse with the extra force from the extra rubber bands. Make sure you reenforce the trigger, too.
I am not sure how thick the card was in the original set, Some of the other models I built from that same group obviously needed some thick card so they would work better. Lots of reenforcement was needed in some. Next time I try building one of them I will print the parts on regular paper then laminate that on to some thick card like the backer board of writing paper pads. You should try the Mechanical Bank. It works good once you tweak the gears to keep it running.
