I use a Laser Comp for backpacking/bikepacking. I don’t usually go off into the hills for a continuous two weeks though. I’ve done a few longer trips that are a week in the hills followed by a day or two in the valley to regroup followed by more hills etc. I did the Munros a couple of years ago like that. The Laser is good for that sort of approach.
If you are going for a couple of weeks away from civilisation at a time, I’d be inclined to get something a little larger. The main issue with the really small stuff is condensation. As the tent is so small, you can’t help coming into contact with some of the damp bits and over two weeks, your down bag (if you’re looking to shave grams, you’ll be using down) will get damper. If there is more than a day or two of rain/damp/condensation, you’ll be glad of something bigger.
