I have hit both but not in the same head for me I did not like the back weighting of the Chrome but the flight was very nice The DI is a great shaft nice balance and i love the feel it just launches to high for me the spin seemed very similar between the two but with different heads it was hard to tell
I have the 70-ish gram versions of both. For me the DI launches a little higher. On a good swing, the spin differences aren't enough for me to bother with. I do feel like the Chrome is more stable, while still feeling smooth through the swing.
