I guess the question is, do you hit your current driver well? If you do, then I probably wouldn't switch at this point. If you do want the extra yardage from one of the Big Bad new drivers, then I guess be prepared to re-learn how to hit a driver, because it is different with a 460 head.
Personally, I think you'd love having a hybrid in the bag. I say this because I just got my first one. I had never even hit one before, and purchased a Callaway X Hybrid online. It's an awesome tool to have at your disposal. Learning to hit a hybrid is SO much easier than trying to figure out a new driver.
So my answer...Go with they hybrid, and happy early birthday.
