Protease inhibitor coctail for yeast?

I seem to be getting quite a lot of protein degradation in yeast
homogenates and subfractions (glass beads to break cells), even using PMSF,
leupeptin and pepstatin.  Sigma cell a cocktail of AEBSF (like PMSF?),
E-64, pepstatin A and o-phenanthroline (metal chelator?).  Is this any
good, and suggestions for a good cocktail.  If possible I would like to
leave out a calcium chelator - would this cause a problem?
