I have had a wide bore snorkel (Tekna) for about 3 years and have had
no dead air problem.  The one thing I did notice is that blow out
is harder and often requires a second blast to get some drizzle out
if the bottom.  The problem ca be eliminated while snorkeling by
using the "puff" method.  When on the surface on the way to scuba, however,
this can't be done.

I would think that prolonged snorkeling using only the blow method
would cause greater fatigue.
