I have been reading some articles lately on effects different solder has on uniformity ( flatness ). I have also read where some solder may be being sold as "pure" solder but in actuality the solder was blended with recycled solder resulting in organic contaminates.  Based on this information I have 2 questions. 

1. Has anyone found improved results by changing the solder supplier? 
2. If positive results where found,  what solder did you change to? ( Please respond to this question off forum so as not to 
    invoke inappropriate advertisement)

All helps is appreciated.
