RE: I am!

John beat me to it with his recommendation! It's all about heat transfer. Smaller tips are great for tight spaces, but generally the limited heating contact area makes for a more difficult and challenging wetting of the surfaces.

My main suggestion when working with high silver content solder is to ensure plenty of ventilation or use a fume extractor as the fumes are worse for you than the leaded solder. Wear gloves to avoid touching and transferring oils and moisture to the parts to be welded. Also avoid the temptation to touch the welds with your fingers afterwards when admiring your handiwork! I was very guilty of that until I realised how quickly dendrites form when the circuit is energised. Electromigration of the silver ions is a real problem with unleaded solder and the dendrites can form within minutes depending on the applied voltage and the relationship between track potential. The dendrites will even go around the edges to the other side of the board!! Track bridging can occur within hours in the presence of moisture even if the weld was perfect initially.
