Yea, they do glow a bit, they look milky really, but awesome, I took a pic of the ball drop wear on my bop, but you can see the slings there..

I like the way they do work with light, and prefer them.....sometimes, Ill mix some color rubber in, especially single posts. Here they are on slings:

More curious how they play, less bounce than rubber?

I'm going to buy some to try them out, but I'm guessing they'll be different enough on the slings to make me not use them. Different bounce? Weird spin on a ball that rolls down the face of a sling?

I see no difference in play or bounce, but then again, my eyes are not as good as others.

On my shadow, or Tommy, the only comments from others are, "too fast"...Which is either from p21S wax, angle, and or rubbers....

Small investment to try and decide for oneself. I also like that they look "cleaner" over time then any color except black.

I mix with Matt, at Titan, with his colors, where it looks right to me.

Who sells these?

I don't see a huge difference in bounce. I prefer the look and the cleanliness of them. Less dusty. I think they look outstanding. I have them on all of pins now.

I put them on all my pins now. I love the look and feel. They are slightly tighter and strech less but I would not say any real perceptible difference in bounce. It can be a bit more difficult to fine tune your slings since they are a bit less strecthy, but no big deal. They stay clean MUCH longer and are easy to wipe down to keep clean.

I do not like how they print their name across the entire rubber and have found this can cause weak spots. I have had 2 sling rubbers break in short time. For the most part it seems there are a few duds and they snap quickly. If not a dud then they last forever and don't wear away at the edges.

I was buying then all from PBLife but liek them so much I just bought 4 variety boxes from Germany and it was worth the shipping then. Hoping they arrive soon.

I've done the same as whysnow and converted all my games. They seem to play like white rubbers to me but stay cleaner and I love how the light works with them.
