Quoted from ABE_FLIPS:
I'm just not sure if I want that key component of a flawless aim since my goal is to get comfortable with standard and bad adjusted machines.
I haven't had mine on a very long time, but I think they're likely to make me a better player because for one, my whirlwind plays faster than it's ever played since I put them on.
Also, it's been touched on previously in this thread, but I suspect the improved accuracy is going to improve my play as well. I'll use the cellar shot on my whirlwind for an example. With the normal flipper setup, when shooting that shot from the right flipper, the exact center of the flipper was the most likely spot to successfully sink the ball in the scoop... but not always. There were plenty of times I'd flip with the exact right timing and it would brick to the right or left of the scoop. Additionally, there were just as many times where I'd know I flipped either way too early or way too late, but the slop in the system would luck the ball into the hole for me anyway. With the halos and precision bushings, that shot is now consistently 2/3's of the way down the flipper. If I flip early, it misses right, and if I flip late, it misses left. The range of where the ball can be on the flipper for a successful shot is really small now, whereas with the plastic flippers and bushings there was a range of well over half the width of a ball where that shot might well go in.
I think it's not so much that these new flippers give you flawless aim, it's more that they give you consistent precision. So, yes, on one hand it does make the game easier, in that you no longer get the surprise misses when you've shot with the correct timing, but I would guess that is more than balanced out by the fact that you also never get the false positives where a badly timed flip makes the shot anyway.
I'm definitely curious what more experienced players and people who've had precisions on their games longer think in comparison to what I'm seeing though.
