Pete, the best PFD is the one you will wear. I probably have 25-30 around here, everything from self inflating to cheap simple vest. As I often paddle alone in some remote areas I need to wear one as my maturity advances. The money spent on the self inflating was a waste for me, for some reason it just seemed to be in my way (if I would lose 30# it might work better) The others were not comfortable in a seated position. I finally bought a paddling vest from Academy, It is comfortable enough that I will wear it rather than laying in the floor of the boat. It has some pockets sufficient to hold a fly box, tippet etc. Try on several, to see what fits you, this is the one I settled on:
