I track at 5 3/8 over for me it very strong position, I do not have alot of tilt probably 12-13 degrees. Later ball motion with a very strong backend reaction.
When I bring the mb towards the VAL, the ball rolls forever the closer it gets to the VAL. Personally I do not like any VAL higher MB balls I have ever tried, I like to see the ball make a motion towards the pins.
To me why bother buying a high MB ball if it is going to just be pure roll and for me never hit worth beans. I prefer balls like Legends for heavier oil's or just use my favorite mb over 1 inch right and below the thumb.
