PTS7 is long, which means thermal transfer is poor. You'd only want a long tip if its necessary to get into a tight spot.
Its also pointed, which makes it hard to get a good surface area of the tip in connection with the lead or part you are soldering.
I don't know why you'd bother returning a $6 tip, just try it out, see if it does what you want. If not get a shorter style.
You can try the suggestion from IanM above.
