All this being said, I still hate my POS sleeping bag. Honestly, that's what begs the question; New TQ or sleeping bag?
You need to spend some time at a few web pages. A topquilt with quality down, rated to -7C weighs 0.5kg. A Western Mountaineering -7C SB weighs 1kg. But, again: If you do the research yourself, the same numbers will have greater effect.
Of course, the toq quilt is narrower than the opened SB. You pay less because you get less. And when temps are warmer than you expect, there is less quilt in the hammock to get out of the way.
BTW: Have you been to Jardine's page (or consulted specification sheets)?
