I purchased a Hilleberg Saivo and took it with us for our month long trip down the Bloodvein River this past August. Everything they say about Hillehberg tents is true. The quality, the design, the materials used and every detail is thoroughly considered. The Saivo is a four season tent so it really is bomb proof but I'm sure you will be very pleased with the Rogen.
Got it today and set it up, it's probably the last tent I'll buy for two person use outside actual winter. When they say "3 season" they clearly don't mean what everybody else means by that. We'll see how it is in use, but my initial impression is that it'll meet my needs well.
