If this gets the "O-Din" seal of approval, I'll be pretty damn impressed...
Always good to see someone trying to improve upon the standard without sacrificing tradition.

Side note,
I went back to traditional flipper rubbers on everything a few months back because it felt like I was cheating with the Superbands.
Looks like I'll be putting in a sample order with Titan to see if they can finally cut the Spicoli mustard.

I think most silicone bands tend to dent/stretch like that.
The clear versions that PL sells did anyway; pretty quickly too...
The orange ones above look like they have about the same wear as mine did.
Corners seem to flatten out over time as well, (see first pic w/orange rubber on that JP, closest to bumper for example) so I tend to rotate them faster than the traditional rubbers.

Make sure once they're installed that you re-distribute the tension (plus any twist) to get rid of the white appearance in the GITD, or any color for that matter.
It will also allow the silicone to have a consistant bounce.
