Installing the rubbers on my MMR was much more of a task than I expected, quite a bit of fiddly dismantling to get to some of them.
Played about 20 games so far after and gameplay wise I can't tell the difference with the post sleeve rubbers and top lane rubbers, the bounce on the top post of the slings seems slightly more bouncy, but the active part of the slings is not noticeably different IMO.
The flipper rubbers (silicones) do play differently IMO to the original rubber, dead bounce is good and not much different to original and shots are good and predictable. But the ball seems to roll slightly faster and further down the flipper than on the original rubber, so a trap that would not have made it to the end of the flipper and rolled back down to be trapped will now roll over the end. So over all I would say game play is ever so slightly harder with Titan flipper rubbers Vs original black rubber, I would prefer more difficult to easier as easier makes me feel like I am cheating.
The purple color looks nice and I am happy with it, but I was happy with the original black also. I would not have bothered changing just for the color change, but the bonus of it keeping my new pinball cleaner is my motivation.
I was cleaning black lines from my in lanes every week, I assume I won't need to now.
Verdict = I'm happy with my new Titans and they are staying on
