Quoted from cubitron:I know I am not adding much to the conversation, but here is what I've experienced on my GB Pro. Those Scoleri Bros. do not drop with a solid hit and often throw the ball over the flippers. My brother calls it the "Scoleri Screwjob". I like the advice of backhanding. I will try that.
Some people mentioned a dirty feed through the spinner. This happens rarely, but it is almost always SDTM.
Finally, I just don't feel right about the left scoop kickout. It never shoots SDTM, but lands unpredictably on/near the tip of the right flipper which prevents most forms of ball control. Our local operator took his kickout power down to 20 so it dribbles out to the left flipper. It works nicely, but I just don't feel right about doing it on my home machine.
This may help with those Scoleri Brothers drop targets...

I picked them up (along with a shaker motor, Zombie Yeti blades, etc) and waiting for my Premium to make it's way down the assembly line. Pinball Life has a fairly decent and affordable selection of GB parts for fine tuning your machine without adding major mods.
