Skyrise,
I've tried both Cabela's GoreTex and Dry Plus II waders and was impressed with both. The DPII's are a little lighter, but still pretty tough, no tears or punctures yet. They are both cut full enough to allow plenty of leg movement and both have double knees with openings at top and bottom for drainage. The first pair of DPII's had a slight leak at the joint of the neoprene foot/leg, but Cabela's replaced it in just a couple of days. It's easy enough to overcome the vapor transfer capability of either one if you're hiking on a hot day or doing much hill climbing, but this is also true of every breathable wader I've tried. But even if you get sweated up a little, you'll eventually dry out. I think my choice would hinge on what you were going to be doing with them. For real brush-busting, I think the slightly heavier outer fabric of the GoreTex version would have the edge, but the DPII's are light and comfortable. Quite honestly, I couldn't tell any appreciable difference in the breathability. Both represent very good value for the money.
