The TE+ or the TS3 would be great choices. One thing to consider is that both have stronger lofts than the Mizuno 921 Forged. Both are 2 degrees stronger. So that fact does not help in you needing more height. However, the shaft choice can help. I think the MPF Pro Series, although a flagship shaft for us, would not be the best choice. It is a firmer build in each flex than the averages of most other shafts. In other words, it plays stiffer. I do like the Rapport Core Blue iron shafts and the Recoil 660/680 SC iron shafts. They are significantly lighter than what you have been playing and you will need to consider that. There are heavier graphite shaft options to consider if you are worried about too big a weight difference, but the heavier you go the less likely you can find shafts that can help significantly with trajectory and distance. Lowering the overall weight of the club, along with a more flexible shaft, are the two things that I would say would give you the best chance to improve your club head speed and trajectory, especially if you move to a slightly stronger lofted iron.

Thanks for the fast response. I will take a look at the shafts you suggested.
Thank you!
