Attached is an instrumentation amplifer I designed for measuring signals of 10mV peak, 25 gain (linear) and a CMRR of more than 40dB. Are there any simple features I can add to it that complements the high precision op amps used?View attachment instampforum.bmp
 

CMRR of 40 dB isn't an issue. Achieving real high CMRR values competitive with integrated instrumentation amplifiers will be mainly dwarted by insufficient resistor matching and T.C. tracking.
