Hi Michel!
1. buy G20 set L59 - you can use it long time, huge difference high trajectory
2. Pw iron 115y, you need 3 wedge. 2 Options:
a. 100y, 75y, 50y - Ping L41 - 100y, Ping L42 - 75y, ATV L39 - 50y
b. 100y, 80y, 60y - Ping L41 - 100y, Ping L18 - 80y (not the best wedge but if you like you can keep it) or ATV L39 - 77y, Ping L42 - 60y
If you will use not very good ball i recommend you option a. Much easier to hit from 30-45 y with 50y wedge then 60y wedge.
3. Putter. 2 Options:
a. you ding - Nike L51, slow meter or Ghost Spider L35
b. you miss little ding. - Rossa Daytona L55
My recommendation Rossa.
All those are too good for tour pro tier. :)
I speak better french too. LOL :)
