My uninformed opinion, but that pad seems an overkill. Weight, volume and the possibility of damage if you leave it in a warm tent ( supposedly they don't like to expand in heat -damages the baffles- and the expense, unless you use it below 20 degrees F on a regular basis. Nice pad for winter, but I'd think twice if you're cutting weight. Throw a piece of Reflectix or a piece of SOL emergency blanket under your torso when it gets a little colder. They both work (use both, as I camp below zero F) and take up little room and add little weight.
