Quoted from arolden:
Yes. 11629s are the strongest type of coil. You should be able to hit all shots from a cradled ball.
Are the coil lug connections solid?
Flippers are not the issue for sure. I have rebuilt more than 15 pairs and I know when they are working correctly (no drag, correct vertical play, bended coil stop etc). I have learned all that the hard way...
I removed the spinner and it made a difference. Now I can make the full orbit on 2 out of 3 times. It feels normal when spinned with finger. Maybe I should replace it. Also I noticed a slight play in the flap in front of the Delta ramp. I temporarely taped it to the playfield and it also improved slightly.
But man is it frustrating with these williams games. Same with T2 ramps. Shots have to be 100% correct or ball won't make it. I can only imagine the struggle with these on locations back in the day with filthy playfields and warn balls.
On Sterns (Star trek for example) not only will you easily make all the ramps and orbits, you can also back hand them. Flippers feel a bit overpowered even.
