One could raise the pole several inches, but it distorts the geometry of the tent making it less taut and the sag actually gives you less room. I know this is hard to believe, but I've tried and it is just not as simple as raising the pole. This is in part because the bathtub floor is attached to the side of the tent via elastic bands. You have to stake this tent way, way out to get it to breath better and the virtual foot print with all the stakes becomes huge.
Condensation is a real issue with the LS as Mary noted, but it is bomber in heavy weather at Chris mentioned.
Ron and Henry both have produced great tents. and you can't go wrong with either one. That said, I own both and I tend to use the Contrail a lot more. There are several ways to pitch the Contrail for storms and fair weather, with a pole at each end or just the front so you can adapt. The LS has one pitch which is very storm worthy. I have weathered very heavy rain and wind in the Contrail with out any problems. For hot or humid conditions the Contrail breaths a lot better. For very cold or frequent light snow the LS probably has a better shape and more protection. These two tents with stakes, lines, waterproofed seams and stuff sack each weigh 25 oz. (+ or- 0.5 oz)
Honestly, I think you could make either one work for you. I think both Henry and Ron will let you buy a tent and set it up in the backyard and check it out and if it doesn't work for you send it back for a refund. So you may consider that. Good Luck.
