yeah, I think barbless hooks - especially on trebled hooks - is a pretty good idea, partly because it makes for better catch and release, and also because, as you say, it'll always make hook removal from one's own flesh all the easier.
Also a good idea for kayak fishing use simply because of the confines of the deck. And especially so regarding things like mesh pockets (Hobie, please, please replace these with a rubber mesh, like modern enviro-friendly nets) and also furling lines on yaks like the AI/TI. I've seen a few barbed hooks impale these before and it can get messy removing them. Infact, it happened to a buddy of mine this weekend just gone. In the photo below Steve was having a hell of a time getting the lure removed from the furling line:
I am giving serious thought to going barbless on my hooks now, for all of the reasons you mentioned, plus the ones I just added.
