Gear choices need to complement your style.

I prefer only the Integral Designs Unishelter for exposed ridges above timberline.

The Ti Goat bivy with a poncho/tarp is a good all around combination for the Colorado high country.

For places like the Grand Canyon a Jacks'R'Better 8'X8' tarp and umbrella are a good combination.

You really need to hike enough to develop a style before you drop a lot of cash into high tech specialized gear.
