If you think it's tough to find a graphite shaft that works, consider the fact that heads are designed and weighted for graphite. Stick them on steel and you have to deal with swing weight issues.
I went through the issue of 3 wood and hybrid being less than optimal for me with the stock Titleist VooDoo Stiff shaft. I simply went to a Titleist Demo day, explained the problem, and we ended up with 86 gram very tip stiff shaft in the 3 wood and a different heavy tip stiff shaft in the hybrid. Granted, I bought 2 new Titleist clubs, but the fitting was free. Much more predictable.
