"Sorry Jon for destroying your thread."
Not destroyed at all :-) What's the purpose of a forum if not for discussion and debate?
Comparing the numbers (weights, fill, loft and so on) only takes me so far, hence the need to enquire about real world experience of the products, but much of what has been said seems to reinforce what the numbers suggest. It was so much easier in the past, wandering into Black's and trying out a few sleeping bags on the shop floor, but with quilts there are so few options that I'm having to buy from the Internet; and returns policies here in the UK are nowhere near as generous as in the US (Oh, how I miss L.L. Bean and REI!)
