The flux is also needed aswell........otherwise you get too many shorts between pins......generally you always have to mop up with solder braid when doing that.....and you often get dry joints  that look wet, but are dry.

i dont think that is a reliable way to do it.

Another vote for a bevel.  :-+ It's by far my most used tip shape.

I've a Gull Wing that rarely gets used as it's just not that much different and I'm too lazy to bother swapping tips.

I see no smiley in your comment, you must clearly have left them out by mistake ??
If not, its utter nonsense you write.

Gull wing tip is what is needed, like others say, I only use the gull wing for chips with more than 48 pins. The <48 pins I use a normal tip (and add solder 1 time for each side of a qfp package). For gull wing (Weller), I can solder a couple of 100 pins 0.5mm qfp without "refilling" with solder.

It's not a mistake, it's treez. For the sake of humor or losing hope in humanity you could read some other threads/posts he left.
