Hybrid/Utility lofts?

[Black_Black]

I'm confused about the different lofts of Hybrids. My question is, do I use the basic loft of a 2-iron (19*) for choosing the correct club? Currently I use a Sonartec Md 19* as my hybrid club. Im guessing that since it creates a lower ball flight is why 19* works as a 2-iron? I am currently looking into a buying a new hybrid, a Titleist 585.H and they recommend 17* as a 2-iron/4-wood, and 19* as a 5-wood.
I know that the 585.H launches higher than the Sonartec but wouldn't a 17* loft produce more distance than 19*?

I am scientificlly challenged but I think loft is only one of the factors determining launch angle and distance. The mass of the club head, the weight, length and flex profile of the shaft, and most importantly the center of gravity of the club head. The lower CG on cavity back clubs is why the lofts are strengthened ( maybe to make us think we hit farther also as a marketing issue, since our PW often carry 9 iron lofts these days). That is why I carry a 4wd 7wd. When I reshafted my 7wood I put a 41 1/2 inch shaft in it. My four wood is shafted at 43. Since the loft difference is only 5 degrees my gap is manageable and I can carry an extra wedge.
