R help - Aug 2008 - limits/thresholds for arrayWeights in the limma package

Is there any limit ratio of between-array weight values, which one  
can get using the arrayWeights() function in the limma package  
<http://www.biomedcentral.com/1471-2105/7/261/abstract>? For  
instance, if one array has the weight value - let's say - 4 and the  
rest between 0.5 and 2, shall I keep the array and use it with the  
weight array, or rather discard the one array and apply again the  
arrayWeights() again and continue to results? I am particularly  
interested in answers related to the mouse 430_2 chips.
