Have you ever bowled on mendez pins??? They have a magnet on the top of each pin were i bowl everyone has pocket 5-7 and 5-10 splits. You can and will leave pocket 5 pins also, it can make a 700 a good night and no one averages over 233. In fact anyone over 220 is ex touring pro or top amatuer level bowlers, Dave Wodka etc. most higher average bowlers do not dare to bowl league here if they want there ego's to stay inflated.
