Hi Allen
I recently used a similar strategy to pcr up a lactate dehydrogenase 
gene and used degenerate oligos with inosine in 3 to 4 positions.
It worked beautifully. I didn't try primers with mixed bases for 
this experiment for comparison but have used them for others and
have never had such a clean result - this could be due to the experiment
and not the primers however....
Personally I would go with the inosine
Good luck
Emma
