Your trigger should be able to reliably push the ball into your shooter when your shooter is at any angle.

We have one of the REV Smart Servo's and the torque is good, but the speed is very slow - much slower than what we see on the robot you built. Were you using this particular servo, or one like it? Sec/60 specs on what you used would be great if you have it. Thank you guys so much for answering all these questions! Very much appreciated!
