It may depend on how you play them. I only use the GI2-S for our easy par 3 courses for XP and I prefer the cheaper balls to higher cost balls. The longest shot I usually hit is around 180Y and they have enough stopping power with full BS I can get close on nearly every hole and work fine with full TS when needed.
I don't play a lot of default tees with them (lower credit ball) because I have always wanted a little more distance and more spin for elevated greens and long irons. That said, I rarely play a ball better than the L11 or L13 Srixon with these irons when I play on the mobile because of all the sponsor apparel equipment boosts.
I have even used the L11 Srixon during clash rounds on the desktop and shot some reasonably good scores. Again, it can depend on the course. Sacrificing stopping power on longer courses can alter the way you play and club selection.
But here is the thing, after watching even top level players shooting into elevated greens with a 3 or 4 iron they don't always get the ball to sit down like a wedge on an elevated green. The ball nearly always releases forward I believe.
If you want to test or compare different balls with the same clubs, I am open to doing so with other people. Just let me know. I have played on both platforms, mobile and desktop, but play a little better on the desktop.
Just a few thoughts from another member carrying the same clubs...
