JeffyDhamer: Do the G25 irons unlock at a higher level?
Sadly, yes, at level 58 or 59. The advantage is they are the first true high trajectory irons, thus give a little more stopping power. Obviously learn your new clubs and do not rush....obviously the higher the level the better clubs become available. If budget is not an issue, then by all means upgrade.
Map your clubs to see the distances for each club, altering the spin and taking notes of how far it goes till it lands and rollout (best in low wind conditions) - BPG is an ideal course for doing this.
Personally I use the punch shot a lot, as it is like using a different club, wind effect is minimised and saves choking down on shots - yes I am talking from fairways.
With approaches, always try to zoom into the green to see the best landing spot and leave yourself an easier putt. Sadly, easier said than done lol! If you miss the green look at the gradients before, to the sides and after the hole as this will determine the rollout.
