I have no experience with these nets in particular. And, until quite recently I was with FlyKs in not using nets, I hadn't used a net in years and had no problems without one. But, then I recently took out a net to make a film and really loved using it. So, I started taking a net if I was going somewhere for fishing (as opposed to going somewhere for backpacking with good fishing).
The net I first used was nylon mesh. I don't think the mesh ever hurt the fish directly (as long as it's not those old-fashioned knotted types I believe you'll be okay). But, my hook got stuck on the mesh several times, and that's what actually hurt 2 of the fish when the hook tip got stuck but the fish were still hooked. Next day I looked for rubber nets. They tend to be expensive, but I learned about the Measure net (http://www.themeasurenet.com/index.htm
). I'm not crazy about the measuring tape on it, but they sell the rubber nets that are fairly inexpensive (http://www.themeasurenet.com/catalog/pr ... ucts_id=42
). I have been using that since and had not hooks getting stuck on the net. As FlyKs said, the rubber mesh is suppose to be easier on the fish, and I believe there are grounds for that.
