Spot on mate,hey can the quarter inch mono netting you use be purchased over the net and is that the stretched mesh size?
i could never find the right size on the internet, i.e. the 1/4" netting. the stuff we use out here is basically already stretched. any bigger, or expandable mesh sizes.....the fish can swim thru, or end up getting tangled in the net.
my buddy was gracious enough to give me some of his netting before he left for hawaii.
the style of catch net i make is a bit different than on the link you show. i use a stainless steel wire to attach the actual net, prevent snags and repair jobs.
here's a pic of my rev. 0 prototype. my new nets are all stainless steel.

its a fun, frustrating way to spend the dive, trying to catch fish. i usually know what im looking for before i start the dive. if i dont see any, oh well. always next time.
