Infinito3010: Changing your game approach is key. It does develop your course management skills. It also provides incentive in understanding what shots one can make in any given situation.
This is so true and to combine that thought with the OPs club question I will say that my approach has changed, literally, and the clubs did it. Having played TMs for the most of 8 months I figured I was as good as I was going to get. Maybe one of these days a 29 or 30 will show up and I'd be happy. The clubs did make this possible.
However, thanks to a bunch of excellent players in a discussion about clubs the G10s kept coming up on top. I gave in and tried them and that's where the approach changed. They are all everybody says they are and that 29 will happen without question, as soon as I master them. I'm stringing birdies on holes I never did before. The 3 foot circle around the pin is becoming almost automatic. The course management has changed too because of these clubs. I can play to better spots knowing I can get over the hazards protecting the pin. (BPB15- favorable wind landed tee shot 160 out. 6i got it to 2 feet of the pin-I have never, ever been able to do that with the TMs.)
Whatever you decide, if you know your clubs and their tendencies you will succeed. GL
