Quoted from MrWizzo:Rather than pull the balls guides out from the playfield as would be required since there are not slats cut in the protector but only holes at each guide's end, I cut out slats between each end hole for the guides, and that worked well.
I'm curious, could just a slit cut in the poly work as well? Instead of that 2 or 3MM gap you created. Does the poly flex enough?
Thanks for the review. That company only has a few EM titles.
