Root kernel for new 2.2 leak

[-ebby-]

I am new to rooting and rom flashing on android. I just installed the rom that is just a rooted version of the leak and i want to try a new kernel. It seems like either hydras or kings are the most popular are they both stable with the new leak? and can i back up the stock kernal or does a nandroid backup do that? I just want a kernel that will give me good battery life and at least the same performance. Can anyone give me some advice? Sorry for the newb questions
