I personally have not used the new nike irons, but I have used the g20's and the taylor made rocket blades, now I have the new steel blades, Really haven't notice a big difference between the rocket blades verses the steel blades. But I have to say the rocket blades and steel blades are by far better than the G20's. And I use a nike level 81 ball, I hit a lot of darts with the steel blade and Nike combination. Never had any luck with the g20's. They won't stick and hold the greens like the other two I mentioned. Don't waste your time or money buying the g20's because it won't help you improve your game and average like the steel blades or rocket blades.
