Thank you for your comments guys, I appreciate your input.

Dag, I didn't ask as to whether or not I should use this kernel, I was
asking for opinions on it.
I'm looking into compiling my own and understand the dependencies involved
with Redhat backported issues.

Thanks again.

Actually, it might be very wrong to run a newer kernel. Sometimes 
interfaces with the kernel change and tools/libraries need to be updated 
to accomodate this change. You' cannot be sure of that unless you have a 
good understanding of those changes. (Especially for enterprise/production 

The fact that you ask that question is probably a good indication for me 
to advise not to change from a CentOS supported kernel. (unless you know 
what you're doing but since you did ask the question... :))
