I don't have experice with either of the fences, but am wondering if there might be a different issue. If the blade is parallel to the table and the fence is parallel to the blade, you shouldn't be seeing kickbacks for the most part.
I guess I'd like to know a bit more about what types of wood you are cutting? Are you ripping or cross-cutting when the kickbacks occur? Do you use a splitter or blade guard with a splitter? Is the blade new and what type (brand and tooth count) is it? Perhaps we can narrow down what is happening when the issue occurs to see if it is the fence.
