I understand and can surely see the negative effects one could have with waders filling up, when I refer to my hip boots, there not actually full length waders like you might think, more so just short of my crotch boots. I have given some thought to the knee boots, but it seems that I hear many many  stories of guys with even knee boots that seem to always find water 1in. over them. Thats my only reason for thinking my hip boots might be a better idea if I decide to go the dry route. I'm still debating  if the water temps will be to cold to go the wet-foot way? Any thoughts of water temps in early May?
