I use a 40W Weller(SP40L) with a fat tip. To get the solder out of the wire holes, I just stick a screwdriver through once the solder softens up. All the extra solder just ends up on the screwdriver, which just falls off.
Yeah, its not that big of a tip... will try to get a larger one. But I was impressed how the ESC took the iron "beating" I gave her only one damaged led
