Yes and no
I use our Tilia Foodsaver some of the time. The rest of the time, I put the fillets in a freezer bag with water. When using a vacuum packer, the item must be dry or your filter will get clogged. I like it since thawing time is a fraction of what it is with a water-filled bag. However, the material is so outragiously priced, that's it's pretty hard to justify. Ours was a gift and I have used it for years for my garden produce. Now that I'm down to a couple of rolls of the 11" material, I'm using it only for whole trout or large catfish fillets. We see no difference in flavor between vacuum packed crappie and those frozen in a water-filled bag.
I am going to try the new freezer bags that have a liner that clings to the food item like a vacuum bag, though. It may the best of both worlds. -Roberta
