Depends. What kind of a tangible difference are you looking for? If you're thinking that it'll make your consistently, measurably faster, you're probably going to be disappointed.
Instead, think about your riding your bike - what quality is lacking that you want to be improved? If you can't articulate the answer to that question, you just need to ride more until you can.
