Jeff,

I have a pair of Simms Headwaters and also a pair of Dan Bailey Lightweights. I switch back and forth to spread the wear. I've had both for about a year, which is about 40 trips each for me. I prefer the Baileys, mainly because I find the lower legs, from the knee down, to be more flexible, and a little roomier than the Simms. I find the stiff, multi layer lower legs of the Simms to be a little hard to remove when doffing the waders. I suppose the flip side of that is that they should resist a lot of kneeling on rocks. Also, I like the interior chest pocket on the Baileys better than the exterior mesh pocket on the Simms. Keeps my camera dry. So far, both waders are holding up fine. I suppose you've been through this, but try on both waders if you can, and do plenty of squatting and kneeling to check freedom of movement. Also try them on with your own boots as you may find the fit is different due to the sock feet materials and designs. Good luck.
