Good suggestions. The other thing you can do, it worked for my buddy, we elongated the screw holes on the deflector bracket and moved it back a bit. For him, after 1-3 didn't work, that did.
Quoted from spidey:1. Drop dead foam on deflector (I did not remove mine)
2. Drop the saucer under the pf with washers
3. Change the right flipper coil to 11630. Don't worry, left ramp and left orbit are still fast. I'm sure it also helps with reducing air balls off the center drops.I'm probably better than 99%, very rare to have a bounce out.
