You don't really need them to give you the specs away, just make sure you know what they are during the fitting and remember them. You should only really need to remember the shaft, length and like angle. Just casually ask if they're not volunteering the information.....you don't need to give...

I had a look at golf.de and there are 'open' tournaments listed, but they seem to require a DGV ID so likely not open to visitors from other countries.
@Oops! I'm in Germany for a couple of weeks next summer. Are there any open competitions where anyone with a handicap can play, like we have in the UK?
I use the Relentless Golf stick with adjustable weights......£69.99 on Amazon. It comes with a 12 week training plan.
You will need a speed radar though, PRGR is the recommended one usually.
You will gain speed doing it....worth the investment in my opinion.
