Deans are really easy to solder IMO. You just have to practice, practice, practice. I only apply solder to the spliced wire Im gonna solder to the deans plug and I dont put any solder on the deans plug. That way I know that the heatshrink will fit over the solder joint. I on the other hand I hate soldering two wires toghether because my soldering iron isnt all that great. I have hot & cold spots on my soldering iron so it sometimes makes it difficult to solder.
