Here's a pic of mine. It's tough to make mine all the time also but that's because my ramp got a warped from a locked on magnet but I actually haven't changed it cause it's harder and i never say anything as people play it

You have the Lightning Flipper mod also which might make it harder to shoot also.

The Lightning flipper is shorter than a standard length flipper. The shot for the loop is almost at the end of the flipper already so if yours is shorter it would just make it a little harder to hit the sweat spot on the loop ramp. I wanted to get the lighting flipper also for tournaments so it is harder to repeat the loop.
I'm not that good in tournaments but some of these guys can hit the same shot over and over again, so making a little harder is what you would want in a tournament. Just my thoughts.

Yeah pretty standard. It stages a ball there and after time the opto will have issues from being attached to the VUK. Had to replace mine last year also.
