I think no more than 2 a side are necessary and if you use the same one in the corner to hold 2 sides as we did last year 4 total is all you need this year.

We used the same thing on 1189 and 3096's bots last year. In my opinion using any other method is a waste of time. Between the two bots the system had ~88 matches of use and during that time no pin ever was dislodged past the ball lock. Let's face it... stuff doesn't fall up. Of course in Breakaway up could vary from moment to moment, but I'm planning to use these pins again anyway.

The specific part number was McMaster-Carr (p/n 98320A140)

They should also mate with AndyMark's bumper brackets AM-0317
