Quoted from Mr_Tantrum:
Sort of reminds me of removable training wheels on a bicycle or gutter blockers at the bowling alley. Are you sure you want to do this? While you've integrated nicely, I would encourage you work on your skills a little more. You can adjust the outlane gaps, learn to side nudge a little, and even set balls per game to 5 instead of 3 to help as you learn the game while improving. For me personally this is a step too far, but not going to criticize you if it's what you want to do.
For me, learning a new game and dealing with it's particular challenges is most of the fun. I don't want to be able to walk up to a pin and immediately set a high score. Heck, I've owned my AFMr LE for a year now and still haven't ruled the universe (gotten very close on several occasions). This is one of the challenges that keeps me coming back to that game, and I plan on enjoying learning and reaching new milestones on JP once I finally have possession of it.
Thanks for your in depth answer and advice. I owe this machine about 5 months roughly and going through exactly what you said, turn to 5 balls for some testing and stuff, get back to 3 and so on. Just to explore the machine. I have half a dozen good pins, but currently I'm playing only this one. . (regularly scoring about 300 to 400, high 700 mil)
I made this mod minimal invasive to have the opportunity to assemble or dissamble in few minutes. My kids enjoy dinosaur and of course this machine very much. But nudging is way out of scope for them (4y, 6y). Especially the 6y old is making great progress. So this mod is helping them a lot.
Since I clean the table regularly, I plan to remove it when friends come to play or if I want to play without this helper.
Sometimes the table is played by friends which are not into pinball at all. Perhaps I keep then the mod assembled.
