That's a really nice review!
One of the things that I've noticed is the relatively large discrepancy in weight for the Trailstar between MLD's website and every other measurement. MLD claims 15 oz, but the shelter usually comes to around 18-20 ounces with guylines, stuff sack, and seam sealing. Stakes will add another 3-5 ounces.
In order to get it down to 15 ounces, you couldn't seam seal it, have no guylines, no stuff sack, and cut off the linelocs!
Granted, seam sealing and guylines are variables so it's hard to list a weight for those, but I still think 15 ounces is a little too low.
The weight breakdown of mine:
Seamsealed shelter in silnylon stuffsack: 18 ounces
Guylines: 0.75 ounces
Stakes: 4 ounces
All in all, its still a low weight considering the protected space you get, versatility, and bombproofness.
Jason, did you see the thread describing how you can set up the Trailstar as a Mid? You don't get a nice zippered entry and have to squeeze in and out of the side, but it works perfectly well. You end up with a 7x7 Mid, whereas the real Duomid is about 9x5.
