Welcome, several of us Ontarioans are on this forum, where are ya from?
If it's 3-seasons you are looking for then the Nest is a great quilt that will cover you easily in those temps. I also have a JrB Old Rag Mountain that I use as a TopQuilt.
Most of the reaction to the supershelter on this forums is lukewarm, you will find most people lean away from it.
You might also want to consider StormCrows 3/4 length quilts: http://www.theperfecttrees.com
They make for a lighter alternative to a full-length quilt.
I have (or had):
JrB Winter Nest
JrB Old Rag Mountain
The only reason I sold the Nest was because I wanted something to easily extend comfort into winter.
You will not be disappointed by ANY of those quilts.
