Hi John,
You already know my opinion on binoviewers, so I won't bore you. Here is a good link, though, if you haven't seen it before. The article is older than the WO binos, I think, but the principles and explanations are interesting. Todd argues that you need big apertures to get the most out of binos, but I find the comfort factor a definite plus even in small scopes.
