The Marvel Pearl and the Code Black with the same layout will be completely different reactions. The MP will bel a lot earlier and stronger in the mid lane. Not sure it will be a good replacement IMO.

Earlier and smoother.  Stronger pin makes the ball flare more which increases traction early, and that strong of a pin puts the core in a very smooth position at the breakpoint.  I do that for heavy volumes up front and/or snappy backends or when I want to tame a reaction down.  If you watch my Code Black video, by the time the ball hits friction, it's virtually pin axis, which makes it get to the spot and then kind of sit there.  Just trying to manipulate shape really.  My usual layout produces flare lines that are pretty close to each other most of the way down the lane, so by the time the ball gets to the backend, the core is in a stronger higher flaring position, which produces a more pronounced move on the backend.

Luke - what difference do you note when you go with the 70x4 or 4.5x35 instead of your usual 65x5.25.40?
