Josep, I am not familiar with the DUI dry glove system, but I use a
different one with cuffs.  I use a small length of vinyl tubing beneath
the wrist seal to equalize the glove, which I can pull out quite easily
if the glove floods.  What sort of exposure times are we talking about?
 I found that a thin ski glove liner (polypropylene?) provides a
significant improvement.  On top of this, use the heaviest Polartec you
can while still keeping enough dexterity to operate everything at any
time (bolt snaps, inflator disconnect, pencil, light switch, second
stage breakdown).  I have long fingers, and use chemical handling
gloves from a safety supply place which fit me better.  These are also
much tougher (less likely to develop leaks) than the dishwashing gloves
normally sold as diving gloves.
