RoadCam - can you move just the ball (while attached to the cam) from 2 or 5 to A or E, and vice versa - without moving the base that the ball sits in? IE. Can the "screw" that holds the ball be unscrewed so that the ball becomes the attachment point, movable between suction cup & 3M mounted solutions? Thus, you'd tighten the screw to hold the ball into the base when you've got the cam positioned the way you want.
Then, you'd only need one low-profile panorama ball (ie. included with all cameras) - and can then have various mounts that can secure the ball that the customer can choose which one to buy (first one free with camera purchase so that they have something to mount to). The idea is that the ball allows multi-axis movement on a permanently attached base - yet is standard size to move between base mounts (for those who need a base mount with shorter drop, longer drop, rear window, suction cup, 3M, etc.)
Hope this makes sense.
