I got the one from Art and it works great. His has some flexibility to it as well.

I second Arts sling protectors and air ball deflector. I have them on a Premium and the fit was perfect. No complaints at all.

Thank you Guys!

Heres the shop link:

To share, this version works on 95% of games.
Small adjustments to take it a few points higher.

This version is cut by Laseriffic! Thank you Joe, and decals are done by Pingraphics.
This is also available at Pingraphics!

The other version is from Joe, a different Joe, at Little shop of Games, with Curly.

He has the same, except rigid, and a newer one that bows out to help with the 3% or so games where the ramp by Stern
is installed a few mm different.

There are also some Templates on Threads, if you wish to make your own.
(I think the $15 I am asking is worth the time savings to make one, but a joy to DIY if wanted)

I have the Sling Protector/Outlane Hop Protector shipping today, and I hope o share decaled pics ASAP.

I will start scrolling through the GB mega-thread, but is there a similar airball plastic for the pros?
