I have been working on an OPD formulation that would not develop any
background for extended periods of time.  Right now, I have two
formulations - a fast version that gives excellent performance with no
background for 4 hours and a slightly slower formulation (~10% less
activity)  that has no background for 8 hours.  If you have an interest in
trying this out, please send me an e-mail to arrange a test spin.
