Re: How to build good bumpers

How do you get an inch of noodle sag? We have never had as much as 1/4" of noodle sag, even before doing clamps and just pulling the fabric tight by hand.

IIRC, the more recent games (excepting 2015) have required bumpers to fit in the "bumper zone" between 2" and 10" above the floor. The bumpers are nominally 5" tall, giving 3" of design leeway. In 2014, when we were picking a big ball up over the bumpers, we went low. In 2013, when we did not have a frisbee pickup, we went a bit higher to reduce the chance of our bumpers and drive getting caught on a frisbee. IIRC, in 2012 (before I was directly involved on the team) we put the bumpers near the middle of the bumper zone as we intended to play defense. Unless you need to have 4+" of ground clearance, I don't know why you'd go to the top of the limits.
