Narrative:

I was flying approach in IMC to remain current. I realized I had the wrong approach plate out. I must have already been drifting off altitude. I reached down to get the right approach plate. When I looked back up, I was 200 ft too high. Corrective actions: have correct plates easily available. Have plane trimmed so it didn't drift off altitude.
