The G25's are good as they are higher trajectory.......but are they game changers? No.
If you have the credits/cash to spend, then they will improve your game a little.
You would get much better bang for your buck getting a third wedge. Dump the hybrid.....you get far better use from your wedges.
The 3W in your bag will need to be replaced as you tier up, but unless you do have the coin to spend, I would only add the third wedge until you hit legend.....then you will need more fire power.
In the meantime, learn all the shots and you will reap the benefits in the longer term. Above all have fun...it is a game.
