Hi Mal,
Yea, the partial fly setup that can be popped out when needed really is great. Ideally, you want to set it up and not need it during the night. But as I said, on the occasion when we started getting rained on during the night, it was really quick and easy to just pull the fly down and clip it into place. Quite satisfying.
If you are looking for something more "Mal" proof like you say, then a combination with the ground sheet is great (but you are going to be spending a good amount of cash here - although maybe you can get it on offer). The Hubba will have the edge in this category, although I think I prefer the Telos 2 overall. It's personal preference at the end of the day though and each has their needs.
Hope you find what you are looking for!
