The Trailstar is a great shelter/tarp, but there isn't a perfect bug netting to go with it. If you are comfortable using a bivy, then the Trailstar is a versatile shelter to get. If you do want a bug net option, then you could try the SMD Serenity Net-tent (what I have) or a bug net from Bearpaw. I have only used my Serenity netting with the Trailstar once on a rainy overnighter in Rainier and I did NOT practice setting it up before hand. The main issue I had was that the optimal height of the Serenity (so it drapes off the bag) and the optimal placement of the corners (to get a good rectangular pitch) won't necessarily match up with the pitched height and width of the Trailstar, depending on what kind of site you set up at.
I think the Trailstar will be my go-to shelter in the "shoulder" seasons, paired with my TiGoat bivy and a polycro groundcloth. For full-on bug season, I am looking at options more like a Lightheart or SMD Lunar, etc.
Also, check out Travis Leanna's trip report from Glacier, where he has a few pics of his 2-person Bearpaw net tent under the Trailstar. The central pole goes through the net-tent and probably fits it better than anything else right now.
