Discovered something in my set that surprised me

[1par2win]

I discovered on Saturday that my 24* hybrid which I bought second hand a while back has a shaft length is 1" over standard (40.5"). I noticed this when I picked up a 19* 909 hybrid and was shocked to find they are the same length. So my question is given the same shaft type (Diamana S flex), same length shaft (40.5), and same model club head (Titleist 909H) would there be much if any difference in carry and overall distance between the 24* and the 19*? Another way to put is what is the singular effect of club head loft on distance?

I don't want to try to go through all the math, but of course there will be a difference in carry length. With less loft, more of the force is transferred to the ball on the horizontal, rather than vertical, axis, meaning, all else equal, the 19˚ will go further. Maybe there wind circumstances where this wouldn't be true, but generally you try to reduce backspin to increase distance (hence clubbed up easy swing knock down shots to prevent ballooning when shooting into the wind), so that should be rare.

Consider that one can even buy entire iron sets with identical shafts (1golf?), where the difference in distance between clubs is entirely dependent on the differences in club heads.
