I don't see any particular problems for R1b people either way. It is just a nomenclature issue. The advantage of the Cinnioglu tree is that we don't have to deal with a new defining marker for R1b. There are just too many references to R1b-P25 to make the change desirable, at least until there is more information about R1b subclades.

Hi David and Ken and all,
The 2005 tree, no matter how official it is or who published it, is very
important to that very small group of us known as R1b, since the old 2003
tree doesn't have M343. David has adopted it, while DNAH has adopted the
awkward Cinnioglu paper tree which stuffs the marker in without renumbering
the clades below it. Think of squeezing the toothpaste tube with the top on
until a new subclade pops out the side. Viola! R1c.
