You have been playing here for over a year and are doing very well. Congratulations!
From your question, I suspect that you have not "indexed' or "mapped" your new clubs. As big a pain in the backside a this action can be, it is vital to your continued success. In each if the 2 times that I have done it (for L 69 and L90 irons), it has cost me about 2 sleeves of balls. Because of this and the time required to actually produce good data, the player who is willing to share his/her data on club performance (for FTS, FBS & No Spin) (and for free - no less) is an extremely rare find - even within the Country Clubs. So you are probably going to have to do this yourself.
Again, you are doing quite well, and I am not trying to insult or "talk down" to you but here are a few considerations:
1. You cannot expect every ball to behave the same - so pick one and stay with it or your "mapping" effort will be a waste of both time and money.
2. Every Golf Course plays differently! Even with the same ball & club, the power required for a 150 yd shot at SA #2 will be different fro a 150 yd shot at KIA #7 (because SA #2 plays much shorter). So it is a good idea to keep notes about how each hole plays on each course.
3. Each individual Golf Course plays pretty much the same - every time you play it.
4. Many of our top players have recommended BPB Back 9 as the best course to "map" your clubs.
5. Only "ding" shots for "mapping".
6. You must hit the ball both toward the green and away from the green to get an average figure for a "no wind" shot..
Continued good Luck : - )
