It's a great technique! I always carry dental floss in my fly box...just in case. (Plain or mint, doesn't matter) Just loop it around the hook, at the bend, push down the eye end towards the skin, and quickly snap the ends of the floss, straight back (180 from the eye). The fly will pop right out. It is another reason to buy barbless hooks, or at least, bend down the barbs before fishing.
