I don't see anyone gaming the GT4, and am curious what the tradeoffs may be going with the 4 over the 3 as I currently game a TSi3 and want to upgrade to the GT. My driver swing speeds during a round are between 125-130mph unless I'm really trying to step on one (I'm 6'7" and was a pitcher for a long time).
I love the shaft I have (Ventus Black 6-x 65g X-stiff) and don't really want to pay to get fit just to try two driver heads a couple times each. I want to limit the spin as much as possible on my driver so i can feel comfortable hitting it when the hole isn't wide open, but also know that I need forgiveness.
Has anyone hit both, or know what the tradeoffs are between the 3 and the 4? I've read the Titleist page on both but was hoping to get some insight from you all. Thanks!
