hi derek
I have the fixed head McLean (not the hinged). I hated the original net - catches on everything you walk past
I bought a mesh style landing net head of roughly the same size, from eBay, and used that. In fact, I've bought two such mesh nets, different each time, and they've been grand. Can't recommend a specific brand; i'm sure if you find one of roughly the same size it'll work just fine
here in action:
cheers
