I ditched traditional hybrids and went to a hybrid 2 iron that I'll really only be using for long shots out of rough and a few other miscellaneous times.
Hybrids are great if you can't hit your irons high. However, I fight a hook to begin with, and I find a hard time finding a hybrid that doesn't tend to shut on me when I'm hitting shots with it...and being so hook-concious with the club mentally negates most of the physical benefits I'm getting from it.
The hybrid I have now is, essentially, a slightly-easier-to-hit 2 iron with a graphite shaft that's probably a touch longer than a standard 2 iron. That's about what I wanted. I can also hit more shots with it than I could my 2 iron.
I think you should play whatever clubs work best for you, and you need to be honest with yourself about it. As 'sexy' as a traditional blade is, I play a forged CB because it's what performs best for me. You have to do what you need to do. Period. If that means, for this season, you carry hybrids from your 5 iron up, then you should do that. If it means you should carry 1 hybrid, or carry a 5W, or a 7W or whatever - you should do that.
