Always get rid of that black rubber on every game!
I did titans on my JP2 and didn't like them, the slim tapered post sleeves are ok but they dont hold up, I put the regular slims on my Iron Maiden and the were beat up in under 100 games.
Put the the tapered ones on JP and I've had to turn all of them to a fresh side because even after cleaning them they are chewed up, it'll be cliffy for me next.
As far as the rest of the rubbers go, too bouncy for me on this game especially the flipper rubbers, the ball would bounce all over the place and I wouldn't even get a swing at it for long periods of time.
Swapped the flippers for perfect plays and it was much better, put superbands on tonight and now it's amazing. I can only describe it as "predictable"
I've had titans on my Dialed in, IM and GOTG and never really had an issue with them (superbands for flippers on GOTG but everything else titan) but for whatever reason I hated them immediately on JP, felt like I had zero control.
Got some perfect play rubbers to put on and see if there is a difference besides the flipper rubber but the flipper rubber alone made a HUGE difference.
If it wasn't for all the crud from the factory rubbers I would leave them on as they play great IMO but I keep my games clean and that's just too much maintenance with those.
