The above should be recognized.This is mostly baloney (with some validity given to the table cloth and conditions...high humidity makes it more difficult to draw with anything)! Tip size, shape, hardness, etc have very small effects on draw. Being able to draw easily and effectively is 99% about having a quality stroke. Tip offset for maximum draw will be the same, whether shooting with an 11mm tip or a 13mm tip. Tips play differently, and your personal observations may hold little weight in actual response.

Stroke is the primary factor that determines ball reaction.
