I must admit I really don't like metal framed cradles, fish thrash and damage themselves, or thrash and get dropped onto metal.
I have 2 unhooking mats, a big Rod Hutchinson Cabrio Unhooking Mat, and a Chub Xtra Protection Mat.
I do struggle with a mat with deep sides due to a screwed back, lifting a fish can be painful, and having to bend over a walled cradle is a killer, so the majority of the time I use the Chub Mat. If I need to use the barrow to transport my gear I take the Cabrio mat as it makes a really handy barrow bag.
The Chub mat folds in half and stores my pod bag and centre bar, my weigh sling and sack, and a spare pair of storm poles which double as distance sticks and camera phone mount.
