Should I update? topic

I am currently running pure NCG and don't have any problems to speak of, the only thing I have done is root. My question is, is there any benefit to upgrading at this time, any gray advantage? Or should I wait?

Oh, and is there any easy way of flashing just the kernel, I'm using Mac OSX 10.6.8 and there isn't an Odin I'm aware of or equivalent. Any help would be greatly appreciated.
