FWIW - I was with Ben Bade on the Illinois trip where 3 dynalites broke. I was seriously considering upgrading to them for myself until that trip. I decided to stick with 8" Carliles for my cat. I've been having good luck with mine for the last few years (averaging about 55 days/year). I haven't chipped or broken one in ages, but I have several with slight bends in them. I usually just bend them back a time or two, then demote them to spare oar duty after a while.
Now that I also have a raft, I might consider getting dynalites because I won't be running the raft on rocky rivers very often. I will be rowing flatter rivers so I think the lightweight dynalites will be worth it for that boat. If and when I do take the raft on something rocky (low water middle fork) I always have the option of leaving the dynalites home and bringing something I'm more willing to break.
