Hey, planeshavings...
I used Walthers Shinohara exclusively on my new layout, and had only one significant problem with them, which I have been told they fixed. It was an ubiquitous manufacturing defect: Nearly half of the under-tie electrical crossover connections (flat conductive metal bits that connect the rails electrically) had to be re-soldered. It was a real PITA, but it fixed them all.
What "contacts on the points" are you referring to?
Is it the little rail joiners that connect the points to the rest of the turnout? If so, another modification I made to all the turnouts was to solder a small wire across that joint, underneath the turnout. Now all the points are positively electrically connected to the rails to which they are attached.
Excuse me if that is not what you were talking about.
