Well, four inches in any direction can make a big difference.
Increasing the width to 30" is a major plus for the many who felt the old Hubba and some other 26" wide solo dome tents, like those made for REI, were coffin-like.
Unfortunately, the pic shows the height has been dropped to 36", too low for many. So with all the new low denier material, they are still taking from Peter to pay Paul.
Guess lightweight tent designing sturdy enough for the mass market must not be very inspiring. There is definitely a niche there waiting for a cottage maker who can get SUL material with a decent HH to make a dome tent. When they do, hope the frame is not hubbed. If there must be only one ridge pole, how about a Phreerunner design with one carbon strut on the ground at each end to hold the corners apart. (Similar to what TarpTent did with trekking poles on the Rainbow.)
Had thought that the Hubba came out before the Copper Spur, but could be wrong about that.
