I have a Moby steelhead net. Great for coho fishing. I keep the handle tucked down my wading belt and the net against my back. A bit tricky to kneel down and net your own coho, but I did last fall on several occasions. I didn't use it on adult chinook, felt they would just trash the mesh basket. Personally I find the net way too big to carry steelheading. Tried it a few times, not for me. However, I bush wack a lot and carry either a sling pack or back pack. Might work if you are more of a vest guy/gal. I've seen guys fishing in pairs, one guy has the net on his back and the other the pack on his back, pretty smart. I steelhead solo mostly so this system would not work for me.
Personally I just dont cast/fish spots where I know if I hook a steelhead I'm 100% SOL as far as tailing it goes. Seems most of the time I can walk the fish down a bit and find a suitable spot to quickly kneel down and tail it.
