Without actually weighing what you describe there's no way to know for certain, but what I can do is describe my hammock and tell you what it weighs and let you extrapolate from that. My DIY hammock is MTN 1.2 XL 10 feet 10 inches long, single layer, fixed ridgeline made of Zingit, two 8-inch Amsteel continuous loops on the ends and no extra hardware like underquilt hooks. I have a gear sling attached to the ridgeline. That gear sling is 1.0 ripstop about 38 inches long. Total weight in the stuff sack for this hammock as described is 14 ounces.
The gear sling and stuff sack together probably add at least two ounces, so the bare hammock is around 11 or 12. Yours would probably be a tad more than that with the longer length, but still under 14 ounces at a guess.
according to dream hammock's calculator is would weigh roughly around 10.81oz at 65in wide since you didn't say how wide. now this is just an estimate and is based on their freebird hammock.
