Mixed reviews on the tubliss. Some love it. Some hate it. Doesn't seem to do well at high speed riding. Apparently the rim strips tend to cut into the inner-tube. Advantages, no pinch flats, run lower pressure. Disadvantages, They are a nightmare to remove on trail if you tear a sidewall and want to install a regular tube.
Bill's suggestion is good with double bead lockers or just cover the extra hole with a good rim strip.
