Hi,
I have decided to settle on stable repertoire for a while, as my indecisiveness in the openings has been quite detrimental to my progress overall. So Taimanov (a little Caro from time to time)+ Nimzo and that's it. 

The trouble is what to pair with the Nimzo. I am leaning towards the Ragozin or the QID. They are both sound and solid. I like the Ragozin's activity and QID's flexibility.

My main concern is finding enough games to test how they feel, which, online is impossible.
I am trying to motivate a friend to play white OTB for a good number of games against me. How would you proceed? I fear we might accumulate games without perspective and ending the night without any more clue about my performances within these two systems.

Broadly, how do you proceed when testing a system/a line? goals, scoresheets, else...?
