Greater impact on launch angle: Loft or Shaft?

As you can see in my sig I am playing a Launcher driver. I have never had a high ball flight but I have a very high ball flight with this driver. I went driver shopping a week ago and could not find anything that screamed take me home. So what I am thinking is either find a ti460 with 9.5* loft or change out my shaft. Driver swing speed is 92-95 avg. What are your opinions?

Id have to say shaft to a POINT. If you get a 13* driver vs. a 9.5* of course the shaft will do more but between say 9.5* and 10.5* the shaft will have more of an effect.

driver loft has the most effect on launch angle and spin

shaft's effect is directly related to the load
late release and aggressive tempo will load a shaft the most
hence, more effect from shaft

a golfer who casts in his/her downswing will not load the shaft enough to see big difference amoung shafts

shaft relates more to launch angle and loft relates more to spin rate

I first bought the same driver you have now, before my current driver. I also hit the ball high with that driver. Soon after I bought that driver on clearance, my pro fit me for irons. He told me to go with stiff. I did that and decided to find a stiff driver too. They had a 9.5 stiff only (I wanted the 10.5 in stiff- I wasn't able to find one on Ebay though). The 9.5 went a good deal lower, but I gained distance. I am now looking for a balance between the two, with the trajectory higher. Recently the monitor said the launch wasn't high enough with my 9.5. I won't know if I made the right move until I demo the new club that is in the mail. What I am trying is a different shaft and more loft. In addition to that I am going with the Launcher Comp. It has the Epic by Grafalloy in stiff. This Comp driver head probably will give a higher launch then same loft in reg. Launcher. I think that you are right to have the reg. flex with your SS because among other things the stiff will not go a far for you, I could be wrong. You can try a number of different things. 9.5 Ti460's in reg. flex are common on Ebay. It is not a bad way to go. If you went with the same shaft you could get basically predictable results. The ball will go lower. If you will get a pleasing flight or more distance is hard for me to say. I want to say yes because it seems like the 10.5 is going too high for you. I am interested in what you end up doing. Good luck!
