A couple of times I had the fly go through the fish and lodge in the fabric net. Then you are on the stream (or leaning over the float tube) trying to get your nippers to cut the leader to let the fish go - even before you start struggling with the fly!
I switched last spring - although I thought of it for a couple of years, wish I had changed back then. Not only is the rubber better for the fisherman - less frustrating - it is better for the fish. Mine is from Wolf Moon, I picked it up in Connecticut on the annual trip to the Farmington.
Replacement rubber bags are available separately, and if the wooden part of my original net had been better quality I would have just replaced the bag - it can't be that hard. I recommend this for anyone with a quality net handle with a fabric bag.
Cheers, Greg
