I've run PM YS20/20 in my 110 and never had a problem with it. 30% fuel may disappear for a while. It seems that the Chinese are shutting down nitro production for several months during the Olympics b/c the factories aren't environmentally friendly, and the Chinese govt wants to portray a favorable image while the press is visiting. Accordingly, the supplies of nitro are getting VERY short. The NHRA doesn't even know if they're going to be able to finish their season.

There's a discussion of the problem on the NMPRA website (http://www.nmpra.org/). Look under the discussion forums in the Q500/Q40 section.
