[sdiy] op amp suggestions for unusual rectifier circuit

[Peng]

I'm building a circuit based on the super rectifier http://launch.groups.yahoo.com/group/synthesizerscomgroup/files/Custom%20Modules/3DHCustom/ 
 and the full wave rectifier: http://www.uni-bonn.de/~uzs159/index.html .
 
The idea is a dual version of the super rectifier. I want to mix one wave's half rectified top with a different wave's half rectified bottom (both waves from same VCO). Thus achieving strange new combination waveforms.
  Can I get some advice on prefferred op amps to use? What op amp characteristics should I be concentrating on.Do I need a low offset type?
Suggestions anyone?
 
Thanks a million,
P.v3
