No experience with that company, but lots with single wall shelters and a quilt.
I've been using Tarptent shelters. There is a learning curve to deal with condensation. After twenty years of using them, I think it's worth it. For one thing, it's easier to dry during a quick sun break during the day. I think freestanding shelters are not worth the extra weight for the benefits they provide, and don't like messing with long hoop poles.
I bought a quilt just for a bike tour, and it turns out it's my favorite backcountry gear purchase ever.
