Uh...8 lbs packed weight? You will likely be miserable when you hit that first little incline. When the GF and I tour, I carry a 3P hybrid that comes in at 6.25 lbs. That's more than I like to carry. When I tour solo,I carry an MSR Hubba Hubba. I am thinking about going lighter.

As someone noted, what is the packed size of the H? You don't want a giant stuff sack hanging off your rack. When it's raining, or about to, you are going to wish you had the easiest tent to set up. When there is a picnic shelter with a concrete floor you can pitch your tent under, you are going to wish you had a free standing tent.

Since you seem to have a budget for an expensive tent, the Big Agnes Copper Spur UL3 might meet your needs, It's got something like 44 sq. ft. of floor space and two vestibules. Free standing. Packed weight is under 5 lbs. Two friends of mine rode across the country with one this summer. One of them in very tall. They had no problems. I believe REI still carries it so you can check it out in the store. If they don't have one pitched they will pitch it for you.
