If you're reading Wiens, that's the state of the art right there. There are lots of ways of coding morphological characters and he's tried most of them.



For a couple of other examples of morphological and combined analyses (shameless self-promotion here), try



Lee, M.S.Y. and J.D. Scanlon. 2002. Snake phylogeny based on osteology, soft anatomy and ecology. Biological Reviews 77(3): 333-402.



Scanlon, J.D., and M.S.Y. Lee. 2004. Phylogeny of Australasian venomous snakes (Colubroidea, Elapidae, Hydrophiinae) based on phenotypic and molecular evidence. Zoologica Scripta 33: 335-366.



The latter paper (not yet posted, but should be up soon on David Williams' site, http://www.kingsnake.com/aho/pdf/pdfmain.html) may be of interest to some (Richard?) for discussion of historical biogeography, including Underwood's idea of Australian elapids descending from 'laticaudines'. Email me for a copy if it's not on the site yet.
