I would suggest using Joey's kernals as ziefie's I believe requries a few extra steps and if your looking to keep it more simple then joey's is a little more simple to load.
I'm not sure this is accurate at all. The process for flashing zefie's and joey's kernels using the Sprint Update tool are the same. Anyone who has been following zefie knows that once you are on ZE14, flashing gets even easier.
Actually, I think Joey's requires an extra step, as you have to load Max's recovery after flashing Joey's kernel. This isn't required with zefie's.
