Putting the Hart right will be weaker. As with anything strength related, too much of it becomes overkill. Whenever a ball is designed, the core numbers and strength of them translate into time (spin time). The faster the spin time, the faster the core migrates to its' PSA. That doesn't necessarily mean it will hook more. When placing the Hart in the "strong" position it reaches it's PSA almost immediately and loses the ability to continue to migrate before it stabilizes, therefore you lose continuation. I tried a No mercy with everything in line 90 degrees, pin above bridge, MB below thumb and even then the move was alot weaker in hook potential than those I've seen with the hart in the track.
