Anything I should consider against the zpacks triplex?
So a lightweight replacement for my REI half dome is the last major purchase I need to make. Have been leaning to the zpacks duplex for a long while. Price is probably the only reason I've delayed so long. I really only planning for a week section of AT or another trail next summer and some shorter stuff, nothing like a through unfortunately....although i would love to work up of a through of the JMT or other shorter long trails like that....
but something that has been troubling me is space. I have three kids, & I'm really hoping that two will join me on some backpacking. I really want to facilitate the option.... and currently watching a youtube that is reinforcing my dream for them, a video about a guy and two sons on the JMT

Anyway, the triplex looks to be the same as the duplex except 15 inches wider, only cost 3 more ounces but a lot more dollars. 15 inches doesn't seem like a lot really making it really an extra roomy 2-man but perfect for an adult and a couple kids....but considering this is primarily a tent for me, its really silly big for one and will take up more space in my pack when I don't need it.....
so I'm hesitant.
Other ideas?
