This alludes back to Sawbones post on lane play being the most important aspect to learn of the modern game.
Virtually all house’s leagues are held on the THS where a shot (a sweet spot) is built into the lane pattern giving you maximum room for error.
You can have the best ball/drill in the world for the line you are trying to play but if you are not playing the lanes properly you will not score close to the highest potential.
Someone who is playing the lanes properly, even if it is not with not the best ball, will score higher.
I have found that most bowlers who think a given condition is tough are simply not playing the proper part of the lane.
I’ll take on any bowler in the world on a THS if they have to play the lanes improperly and I can play the sweet spot.
You must first find the proper line on the lane and then adjust balls if needed to maximize carry.
