If you're looking for versatility... Centennial is the ticket. I rarely leave it out if an IPA. I also saw a list a couple years ago and cents were the most widely used hop in commercial IPAs.
Which is probably why I rarely use Cents in an IPA. I can buy a dozen commercial IPAs that taste like that at any of my local bottle shops. Good hop though. It compliments EKGs nicely at low levels in British Pale Ales, and is really nice with Motueka to enhance the citrus note.
I find it more of a bargain to buy pounds to half pounds. But be we warned, if you start buying in bulk, prepare to have your freezer full if hops within a year lol
+ 1 - when I told the wife I needed a chest freezer for brewing she thought it was for storing hops, not as a fermentation chamber.
