Thanks, woodcraft. That's the kind of data I was looking for. I have a "V" too for the bungees and bought 24" versions. I would like to minimize the footprint of the under the rollers platform and a 24" bungee in a "V" will provide way more than 4-6" of fore/aft travel.

Think I will try 12" or 18" bungees and see what that creates.
