Unfortunately, surveys will be scarce for Austrians as they are for Germans. It might be a better way to invest some Euros in the game. 10-20 € per month are good for a lot of fun!
Aber langsam mit den jungen Pferden!
First question is, do you want to progress? Any choice of new clubs
will support this, elevate you to higher tiers and cost you more for new
equipment...
The club advice is good once you have custom irons - no real need to put three wedges below the Starter PW of 90 yds.
Second, you don't need many birdies now. With a 72 average, you will proceed to Tour Pro (faster greens there). So, relax.
I propose that you get two short Cleve wedges to replace the $§%$" Starters.
You might then want to use the 3WD as a driver replacement...
The putter, driver and irons are good suggestions, third !quality! wedge to replace the hybrid afterwards.
Viel Spaß!
