Now that the meta designs are relatively evident, I see both advanced trays and tray db4s remaining prevalent for quite some time. Both of these designs use intake rollers to pull cubes onto a tray. This begs the question, what kind of intake roller is best? This post is a general purpose question to see what’s working well for the community.
Intake rollers need to provide enough compression to intake 11 cubes (in extreme instances) while also allowing stack deploys to remain unaffected. What is the ideal length of flap, size/ratio of sprocket, and frequency of flap (links between flaps) to achieve this most efficiently?
