Check out the new Sonubaits Pro Expanders. Just had some this week. No pumping required, they sink straight out of the bag. Simply soak for 30 minutes the night before, drain off, into a bag, expel excess air, into the fridge. (You can also let them soak all night if you prefer). Next morning, perfect hookers. Not sure what they've done to make them sink dry, but they've patented the process and the end result is perfect. Definitely worth a look.
