Personally if this is indeed a 50*F quilt I think snaps are overkill. I used my quilt on my 50+ mile hike in 2011 in late June and I NEVER put this thing in footbox mode. Just draped it over me around 2am when it finally became "cool". My set up with the lacing seems perfect for the particular weather I will be encountering in the summer season which is what this quilt is meant for IMHO.
