I have gotten used to the pencil tip, but it is a little different - you kind of have to draw the solder around the wire. The similar ones that are just slightly dull flow the heat all over the copper and the lead a little better. For example, I would probably recommend "B" - although the pencil tip actually gives you more control once you get used to it, but it also takes just a bit longer to heat up the joint.
By the way - be SURE to check your Hakko model number before you order a new tip, I have seen different tips designated for different models of Hakko soldering guns.
