For me, the answer was not "just a ball", but a drilling to match it.
Everything reactive has a bit too much jump on the backends for me, so I toyed around with plastics and urethanes. Some urethanes showed a bit of promise, then I accidentally came across a drill pattern that allowed a ball to do just as you are asking for.
I have since drilled three balls like this, and they all have the same basic characteristic, a smooth rolling backend with continuation.
I had a granite gargoyle, polished killer instinct solid, and an impulse zone all drilled with what my driller called a "zero" degree drilling.
The way they are set up is with the pin below the ring finger, 2-3 inches from my p.a.p. with the cg on the p.a.p.. On the K.I. and the Impulse zone, the m.b.is well past the v.a.l. on a line perpidicular to the grip centerline.
The cg's are drilled out to get the sideweight back to legal. These balls are versatile ( for me anyway ), and are capable of covering a wide range of conditions, depending on the surface finish.
Might not be the answer for everyone, but it sure helped me with a multitude of problems I had with reactives being too "jumpy" on the backends.
