I am sold on it and I don't even use the high end Callaway balls.
Use it with the Cal legend Z balls and you'll be spoiled.
I switched out my Cal Legend Z balls last night and used the Tour Gi3-D balls I had in my bag for a couple practice rounds on BP and Kiawah.
#1 BP - Only carried it 287 compared to the 303+ over the trees with full BS.
#2 BP - Using the draw shot aiming at center tree and hitting meter at first line it just about didn't carry past the rough on left side of the fairway.
#4 BP - I put it in the rough just past the bunker where I can normally carry that same spot with no problem. Not really an issue since it's a 3 shot hole anyway.
#5 BP - You can't cut NEAR as much off here to get down to around 75-80 yrds on the flat part. I only managed to land in about the middle of the hill and roll down to 100 or so I think it was.
#9 BP- Forget about carrying that bunker with the GI3s cause it's not gonna happen. Maybe with a strong tail wind but I was playing with low wind settings.
I could go on to tell you about Kiawah but I think you all get the idea. Kiawah probably has more areas where you need the extra carry over bunkers and waste areas.
I made the switch to the Gi3s to try them out because the Cal Legend Zs are so freaking expensive and only last about 27 to 36 holes. The problem is I'm spoiled with them. It would be extremely difficult for me to switch back and reconfigure almost every club excluding wedges since those seemed about right in line distance wise because of the roll out.
I know some of those distances don't sound like you gain much. But I'm way more accurate hitting an 8 or 9 iron instead of a 6 or 7 with the G10s. 10-15yrds makes a huge difference.
