Difficult to say what combination will accomplish what you want. The primary factor in trajectory and spin is the loft. In looking at what you describe, my first thought is that the 10 degree with the R flex might be the best combination to try to reduce spin some and still generate a playable trajectory. They are both slightly draw biased in weighting, so both could assist in the fade. With the rearward weighting as well, trajectory is enhanced, so that also leads me to believe the 10 degree with the more flexible shaft would be the place to start. Without having the ability to evaluate in a dynamic fitting session, it is impossible to know. There could be a combination of shaft weight and flex with the 12 degree that could perform well too. Since you have the Titleist at 12 degree with a Stiff flex and it generates a trajectory that is too low, I would not duplicate that combination. I don\’t know exactly how the Titleist head is weighted, but the fact that it in a 12 degree with an S flex generates a little lower trajectory, leads me away from the stiff flex for sure. If you want to error on the higher trajectory side, you might try the 12 degree STw2 with the R flex. If you want to error on the mid trajectory side with possibly a little less spin, you might try the 10 degree with the R flex. Only suggestions based on the information given, but based on how we know the STw2 plays, there is at least a little logic behind the suggestions. Hope this helps.
