I just would not go on the rocks without my korkers. Like someone mentioned above, it doesn't mean that you
won't slip, but it definitely means that the likelihood of it happening is seriously reduced, and that, if you do go down, the studs are going to help you to get purchase during that all-important period of trying to stop the inexorable slide toward the water and get back out of the wave's reach !! (Been there, done that, and VERY glad to have the korkers).
I use the 1100's, which are the lace-up ones. These are a lot cheaper than the 5500's (buckle), are much lighter, and feel more secure with a double knot, IMHO. I have been told me that there have been times when waves/rocks etc have resulted in buckles self-releasing, which is not a good feeling at any point on the rocks....
The studs appear to wear down reeeeally fast, but the replacement tool and spare studs has been a great investment - I check them before each foray on the rocks, and it takes a minute or so to replace with new ones, once you have the hang of it. Last season I went through a bag of 15 or so studs. Just knowing that all of them were working well is a good feeling at dark-thirty perched on a rock!
I know it comes down to a personal choice, but my choice is that I will not go on the rocks without them!!
