born2roam, here is my logic
I've got an HG Winter Palace.
Let's say naked it weighs 9.9 ounces (ish).
The HO Dirigible weighs 16 ounces.
6.1 ounce difference, but within that 6.1 is an overcover
and an undercover and it's already proven to give 14F additional warmth.
The Dirigible has multiple set up options. The tarp has just a couple.
But the setup time and line entanglement was the primary issues.
