   Yes, those are all among the features I tried.  I was using a hunting
   technique to optimize weights of various features rather than neural
   nets.   I know it's tempting to hypothesize/hope that if you combine
   enough bad predictors in the right way, the bad will cancel out leaving
   something good.   My conclusion is that in this case, it's a waste of
   time.

Dave, 

Even though  I've done it  myself on occasion,  I hate reading  a post
where someone says, "I tried that and it doesn't work." 

I'm more interested in the speculation or intuition about WHY it didn't
work.   I'm also interested in what you "hunting technique" was.  Was it
some kind of random or population based searching?   

- Don
