Stick Dimensions

Hey, so I’m back to do some quick research for a possibly mass produced by hand joystick. What is your guy’s favourite stick dimension. I usually like a heavy low profile wide base with plenty of space to rest my wrists. Not very nice for portability but fantastic to play on either lap or table.

ya and if i were to use a solid piece of mdf for the control panel and route holes for the buttons, how thick of a piece should i use?
