So I finally got around to trying to address my ball hang up issues. Quick recap, on Flash Gordon there are ramps with spinners right at the entrance. The spinners help trap a slow moving ball that failed to climb the ramp. Combined with the new protector edge on the lower playfield, this meant hangups at the ramp entrance were far too frequent.
My first attempt at reducing the edge that was causing the hangups was to add some mylar spanning the edge of the protector to the ramp.. to create some help with the transition. It helped, but hangups were still common.
So my next attempt was to shim the ramps up to make it more aligned with the new level of the protector. The easiest way to do this would be with some piece of the protector itself since its the same thickness we raised the playfield level. Lucky for me, I had a protector that had been chewed up in shipping, so I had some extra material to work with.
Using scissors, I just cut a piece that would match the footprint of the bottom edge of the ramp and the recess the ramp sits in. It's just a simple rectangle, and I trimmed one corner due to the spinner. I put it under the ramp with the protective layers still on it, and marked the screw positions.

I drilled holes matched to the screw size and just slide the piece under the ramp. I kept the mylar I had used originally as there is still a gap between the ramp and where the protector starts and I didn't want hangups in that gap. So here is what it looks like afterwards...

You can see there is still a small gap between the ramp and the protector (about 1/16") and that's due to its location.

Play testing so far.. the improvement is significant and I haven't had a tilt-requiring hangup yet. protectors you may want to consider including some scrap material or cut pieces for games that have these kinds of ramp transitions. It was trivial for me given the spare material I had, and I'm sure there is plenty of this kind of scrap from the cuts you normally have to make. I used pieces about 9/16" x 2 11/16" qty 2.. so if you have pieces that are just about 3" x 2" that would have been plenty.
I have yet to address the star rollovers.. but the ball is usually moving much faster in those areas, so I'm hoping that is less of an issue. I also adjusted my inline drops to be level with the protector as again, slow moving balls could get stuck with the unadjusted height.
