Shelter choice has much to do with where you are going and the time of year. I primarily am a hammocker. However, I also use a poncho shelter if the weather is mild and hang points (trees) are few...I spend a lot of time in the desert. I don't much like bivy's...there are some one/two person tents that are just as light and provide a place to keep your stuff dry. I've hiked Vancouver Island some and found it wet/cold. Hammocks with rain fly's work well there but I'd probably opt for a decent ultralight tent next time. You'll appreciate the dry shelter.
