i will answer my own question with regard to the "gearing" englishwhen a ball hits a rail nose at an angle isnt there friction between the two?
wouldnt that cause some "rubbing"
similar if the ball is touching the cloth surface even if sliding
isnt there friction between the ball and the cloth
wouldnt that cause some "rubbing"
i assume patrick the english complements the rebound angle so there is no "fight" on contact
but there still has to be friction for the gearing english to take hold
