I have a EE Convert 20f -6 850fp (2017) quilt which I love, but as it's the XL/XW the weight is 900g. The sizing is based on EE's recommendations of my height and being a stomach sleeper. I run pretty warm when walking, but I've had times at when I've gotten really cold at the end of the day and the current quilt has been amazing to warm me up and keeping me comfy. I remember an autumn hike in the mountains in NZ, where it was very windy at the top and still wide areas of snow. We stayed in one of those tunnel huts. We had a stove running in the evening, but the fire ran out when we got to sleep. I remember waking up in the middle of the night freezing, but I zipped up and cinched down the ends of the quilt and breathed through the small hole and I was just fine. Another time we were camping in wet but not too cold weather, and the versatility of being able to open it up was great, as I was never too hot. If I was to get a second quilt for 3 season use in England/Wales/NI/Central & Southern Europe, would +5c be enough, or would be better to have 0c rated? I know it's all very subjective, but though I ask some experiences. In Nordics I'd know what to use. That and sizing down a bit, I could bring the weight down to about 600g which would be a decent weight saving. I do a Drop Pine quilt which is nice, but a bit short if it gets cooler.
