The Spectrum weighs the same as my Bibler ElDorado. Have you ever set up a single wall internal pole tent in a storm? <img src="/forums/images/graemlins/blush.gif" alt="" /> <img src="/forums/images/graemlins/grin.gif" alt="" /> When you have, you will apreciate the difference between it and fighting what is essentially 2 tents that have to be set up, and one isn't water proof. <img src="/forums/images/graemlins/frown.gif" alt="" />

The ice that you mentioned on the underside of the shell on a double walled tent, would simply evaporate off through my Toddtex tent. A roof vent makes a tremendous difference and is available on very few double walled tents. <img src="/forums/images/graemlins/tongue.gif" alt="" />
