By looking at your stats you are hitting lots of fairways but not hitting that many greens. Your GIR is low and your scrambling stats are very low. It's easy to see why this is, it's because you bought new woods and a putter but you have starter wedges and irons.
If you'd bought wedges first you'd have got those approaches much closer to the pin and your putting would automatically become easier.
When you become a Master you'll need (All together now) 3 evenly spaced wedges and no hybrid. Have a nice day.
