I forwarded your question to Geek Golf and they replied on Friday
Yes, the DCT does launch the ball lower, so a lot of players move up a loft - from 9 to 10.5, 10.5 to 12 etc
Whether you should select 7.5º or 9º depends on several factors:
• Driver heads have a tolerance of +/- 1º, i.e. if you select 7.5º it can be anything between 6.5º and 8.5º, if you select 9º it can be anything between 8º and 10º
• The launch angle of your club is caused by your shaft, weight of shaft, tip stiffness, flex, location of kick point promoting a low, mid or high ball flight?
• The ball flight can be even influenced by the size of your tee, lower tee = you hit the ball on the lower portion of face = less loft = lower flight. Higher tee = you hit the ball on the upper portion of face = more loft = higher flight
• Your swing speed
