There are a few other things you can do. Wash a box of new rubber to remove any grit. Sit in a chair during your favorite movie and run the rubber through your fingers inch by inch. Look for nicks, bubbles, separations and splices, and cut them out.
You might also want to separate your ten pound box into spliced sections. I have found 4 to 7 splices per box, and each is a different blend with slightly different properties. Label them, and store them in separate baggies. One might be Super super sport.
O rings are a convenience. Anything extra Is bad. Some extra things are necessary.
Remember the quote from St. Exupery,
"You know you've achieved perfection in design,
Not when you have nothing more to add,
But when you have nothing more to take away."

BTW, van Dover needs lots of help with USIC 2011! Let's hear from you.

It seems counter intuitive, but many very experienced indoor flyers use plastic tubing for o-rings. Personally, I prefer the hard plastic o-ring to a rubber o-ring. I find them easier to hook up. I read somewhere that someone boiled their plastic o-rings to remove the sharp edges, but I have never met anyone that told me they actually do that. If the sharp edge were cutting into the rubber I would expect most of my motors to break at the o-ring, but again that has not been my experience.
