I've used some Of Chris's replacement ferrules in the past, and unless He's changed materials since then, I believe them to Be the same stuff that I use, so If It's that yellowish/tan looking color, then He should have You covered with what You need.
Like He mentioned the splitting is usually caused By the large tenon size, making the side walls of the ferrule thinner, therefore weaker and more prone to splitting. Over the long haul they can get even thinner. basically If You do not reduce the tenon size, then the same issue could arise even after replacement. Reducing the tenon size usually solves the problem, and I've yet to hear of any complaints of drastic changes in feel, something that would be a concern of mine, just about anytime I had to change a tenon diameter from original.
