That machine will be lobster elite 5 ltd edition, but accuracy of that machine is very poor on flat shots & location (18 or 24 something on panel)..also 35 mph min speed. you can't change speed for many drills..all pre-define..not very usefulWhy would you want to be able to randomize spin? That would not really help with grooving shots as it's only repetitive shots sent to you with the same characteristics that allow you to do that.
It might be helpful in triple oscillation mode to help simulate match play a bit more realistically but for that you really need a match play mode which the Spinfire Pro 2 does not have.
What other machine randomizes spin?
