Brett, I have the old Montbell UL Wind Jacket and that's part of why I'm not considering the pants. The weight is right but the durability is a concern and no leg zips.
I looked at the ID eVent Rain Pants and they are definitely tempting. There are great reviews at BackpackGearTest.org but they weight over 10.5 oz and the cost is high though secondary. If anyone knows of an Event pant at around 6 oz. and below, I'm certainly interested.
Here's my logic for not choosing a 100% solution (Event). Currently when it rains I just remove the legs on my convertible pants and let my legs get wet. I might add a layer to my core if I needed to compensate for cold legs. With the pants, I'll be wearing shorts and let my legs get wet until I feel I need the pants, or it will be cool enough that I'm already wearing them. This is why easy of donning with shoes is so important to me. With this approach I rarely need rain pants for any length of time. They don't need to work 24/7 because once in camp I can dry them out in my shelter and damp legs don't necessarily bother me. In the Colorado Rockies, where I usually roam, I'm thinking Event is overkill for the weight. In a location where it might rain for days on end, Event would be on my short list. I could be totally wrong and I'm open to other views. I'm also looking for something to keep water from running down my legs and into the Rocky's Gortex over socks I plan on buying.
