I install the new inner bead lock system from Nuetech, the same creators of Tubliss. For race scenarios, I think the PROLOCK 360 is a fail proof setup that will not leave you stranded on the side of the trail. The previous system needed you to replace the inner bladders ever so often because they could still potentially pop and fail. Their newest rendition is a 360 degree mechanical inner bead lock.
I pair this bead lock system with their new mousse style called 5150. The new mousse is concave on the inside part of the rim to make space for the old style Tubliss and this new inner bead lock. The exterior of the mousse is grooved to assist in the use of slime to help plug tires if you get a slice. I have been very happy with the performance of this new setup so far.
Follow along at http://tubliss.com/ for the launch of their new product. Hopefully sometime soon.
In the meantime, you can get their mousses on Rocky Mountain that I still run in my practice bike as well from time to time. I have yet to try the new system in the front tire, but am using their Platinum mousse up front.
