Quoted from camcamaro1991:
I would pass on Arts protector only stops the right target before the the ramp, the left target does nothing to stop airballs, the material on Arts, does not cover enough of the left target to stop air balls, infact not even 1/2 the ball is covered when it hits the target (I even modified it to as per his recommendation). Also when ball goes up the ramp it grazes the protector, slowing the ball speed up the ramp, even modified and washers.
skip Arts and choose a better design.
Trying CPR9999's set of 2, will report back later.

Dude Arts protectors work great so stfu already. You're not going to make to many friends here being a new member and coming on here and publicly trashing one of the nicest and most well respected people on this forum. Art did a HUGE favor to all GB owners by making the protectors for this game. You should be ashamed of yourself for real.
