To begin, start by shooting at the 10-pin; aiming at the fourth arrow. Pick a spot on the approach with your feet that you feel comfortable with, and then use your plastic ball with an end-over-end release to make the 10-pin. An end-over-end release is achieved by allowing your thumb to lead your fingers at the point of release.
Low-ball - Wikipedia
When used by buyer, the low-ball is an offer for goods or services far lower than the price the buyer is willing to pay, made in the hope that the seller will at least counter-offer a price lower than the original asking price. Sellers looking to maximize profit but expecting would-be buyers to haggle may conversely make a "high-ball" offer and ...
