haven't been happier with a purchase ever. shot 73 on a par 74 course with two bogeys after work.
Congrats on your purchase. But on the physics/mechanics...

Higher backspin increases carry (provides lift), and higher ball flight increases carry (with any normal trajectory), so lower backspin and lower ball flight would both reduce carry, given a fixed launch speed. Your distance/carry could be increased due to less energy loss at impact, which is true when spin decreases and when launch angle is lower, but that is due to higher ball speed rather than due to less spin. This trade-off works as swing speeds increase.
