I have done sections of the PCT only about ~100mi, I just wanted to give you a heads up that I have had/ or have the SL-1, SL-2, SL-3 and SL-5, the weight they advertise on the website is sometimes is not true. The flysheets are close in my experience but the SL2 nest was way off. I can say that they are very very high quality, strong and sturdy, the SL-1 flysheet will take about anything if you mind carrying the extra weight if you want wind protection.
For example, I just picked up a SL-2 nest this month
SL-2 nest
listed weight 24 oz
actual weight on my scale 28.35 oz
I just spent an hour seam ripping the floor off, and making a silnylon floor
