I haven't done much hiking other than summer hiking and I'm looking to expand that to 4 seasons. I'd like to stick to two sleeping bags; one for 3 seasons and one for winter. The two I'm thinking are the western mountaineering highlight and versalite. The ratings are 35* and 10* and weights are 16oz and 32oz. I figure these give me the most warmth for my weight. I sleep a tad on the cool side. Any concerns that the highlight would be too warm for summer (can it be vented well?) or the versalite would be too cool for winter? Most of my hiking is done in the SW Ohio, SE Indiana, NW kentucky regions. I'm more concerned about the warmth of the versalite than I am about the highlight; wouldn't seem like much of a difference between a 10* and a 0* bag to me?
