Manny65 and thechakapakuni you are spot on regarding the mode hole behavior.
The impetus for me attempting this project was my restoration. I went from the weaker flippers FL-11630 to the stronger flippers FL-11629 (the FL-11629s are the one's called out in the parts list). Not only that, I now had a nice waxed clear-coated mirror finished playfield. My IJ is SUPER fast. I can easily hit the right ramp with the right flipper. I believe this is how the game should feel... it doesn't feel like a widebody AT ALL. Air balls were also a HUGE problem, solved with Davi air ball protectors. With a nice clean restoration I naturally installed a Cliffy around the hole, but this also causes excess bounce; ESPECIALLY with the higher power flippers. My newly re-minted IJ was absolutely perfect with the exception of the mode shot... I had like 95% failure rate and was relegated to hitting it from the left flipper (yuck).
I tried TONS of different scoop designs. Parabolic scoops, deflectors with built in rubber stoppers, V shaped, Z shaped, U shaped... all worked in some way or another on my machine but didn't hold up in beta testing. Eventually a design emerged that seemed to fit the bill. I needed to hit that money shot from the right flipper and have it work... the deflector I have today seems to have the right stuff. Nothing is perfect... there are trade-offs with everyone's take on fixing this problem. I shot for perfection, although I don't think I've quite achieved it (which I am totally ok with) however I think I've come close enough for the majority of machines that are plagued with the issue.
Here are a few key points regarding Lao's Antidote, what it is, what it does, how it differs from the factory deflector:
1. It has a pivoting inertial damper, you may not see it in some of the pictures. It is a very heavy gauge strike plate that absorbs the energy of the ball.
2. It has ball-directing ball guides on the left and right side. These tighten up the shot and change the trajectory of the ball slightly.
3. It has a rigid frame. Normally the plastic allows quite a bit of ball bounce in the cavity. This being metal eliminates that.
4. It serves as a virtually indestructible plastic protector. As you can see from the pictures the Antidote's footprint provides significant protection to the mode hole plastic.
I tell everyone that has modified their mode deflector, especially by removing the stock deflector and adding padding. If you expect Lao's Antidote to behave like that... it will feel weird and you may not like it. When you remove the deflector and add padding, you make a very soft easy to hit shot. The Antidote is does not do this... you will also not hear a "thunk" ... the Antidote sounds more like loose change because of the pivoting deflector. The primary goal of this product is to provide a universal, very simple easy to install... no maintenance solution to mode hole rejects, as compared to the factory deflector. The success of the Antidote was not measured against anything other than playing the game, making controlled shots to the mode hole. There were a few slight tweaks to the design from the initial version, nothing major.
I hope this helps and I hope that those who are using Lao's Antidote really feel like it has upped the excitement of the game.
