Unfortunately some net makers don't list the weights on their sites, I'm looking for some companies that make lightweight nets that I can use when fishing alone. A nice ultralightweight net w 4-5 ft shaft would be the ticket! Let me know what you guys like. 

My Ego is a great adjustable net but it's stout for one hand netting jobs. My Frabill is slower to adjust but much lighter. Hope that helps.

 Past 5 seasons, this Frabil Conservation Series unit

has scooped up a few respectable brown bass for me.

As well as some plus size 'other species' type creatures. 

It's light, sturdy, very maneuverable & extendable; although I rarely use that aspect of it.

Frabil generally has something for everyone. Don’t know the model no. but similar to what you are after. 

I have a Bearpaw net that is very well built and pretty darn light too.  They're very well priced too.

Frabill Titanium Trout Nets are the lightest I have seen but they can be pricey.
