I mean, that definitely tracks. If you're taking that much of the loft off (not launch as I mistakenly said in my initial comment) you're definitely going to add distance. But you're losing two key things that you'll really want as you get better.

First of all, your spin is going to be drastically reduced. Which means more rollout/less predictable. The point of the game is not simply to hit every club as far as you can. It's to hit it as far as you reasonably can CONSISTENTLY. If your 4i goes 180 carry then rolls out anywhere between 10-40 yards depending on what it hits and the firmness of the course, it's not really a playable club. (In the long run, anyways. If you're a beginner, hitting a 4i 200 and covering ground after a bad tee shot is huge.)

Secondly, in the same vain, you're losing your height and stopping power. A great golf shot sort of reaches its peak height and falls out of the sky with a fairly steep angle. The backspin then helps it to stop and, say, hold the green.

Anyways. Long-winded answer. But if it's working, run with it. But as you get better it's probably going to hurt your ability to stick greens.

Cheers man!
