Lots of my fishing will involve blackberries and brush. As I have no experience with neoprene or breathables, I am skeptical of how well they will deal with these things. I also wonder how much the floatation factor of neoprene will inhibit my wading ability (I often go in up to my waist). The rubberized ones I have now are too small to provide good mobility but I am impressed with their lightweight and durability (20 years of use and no leaks!). Thanks for the info
