I bought both the BCS Grande and an 8-man at the same time. I got the 8-man in the 70d material. I love them both. The 8-man obviously has a lot more room to stand up but it's also quite a bit more bulky. Mine with all the guylines, linelocs, stovejack, seamsealed and half liner is just over 9.5 lbs. The carbon fiber pole is barely over a pound. I plan on using the BCS as my primary packing shelter. I'll bring the Grande if necessary. The 8-man will be a basecamp shelter near the truck.
I guyed out my BCS a bit differently than ND's pics. I ran a long single line from the center rear point so I can use a stick or pole to raise it. I also put linelocs on on all the guyouts. I got them from z-packs and they use a ribbon so you can easily attach and remove them from the guyout. By using a single line from the last side guyout you can really get the shelter taught over the back area.
Seems like it would be great for a backpack shelter as well for 3-4 guys to share the load.
