I'm a high tracker and it really depends on the ball and the flare capabilities of the ball. Sometimes even the lowly Fab Blue Hammer with a pin-in near the center of the grip, on dry backends will thump. (strange)
And then again, on the Track Machines (dynamic Robo Core Asymmetrical) the ball tracks quite aways from the fingers and the thumb (with long pin), with balls setup with strong MB. Makes me think I want to try a pin-in/ pin under fingers type of configuration with one of the Machines - for a more gradual controllable arc look on the lane.
But then again, thinking, why risk trying when I know I can create a different mid roll with different wrist, hand, and finger positions on the ball. If more arc is needed we go with the Pin closer to the PAP and kick the CG/MB where the reaction/break point is chosen to be seen. Granted Pin-ins would give a earlier more gradual arc.
If your willing to experiment, have the time and money, go for it. With all of these different covers and weight blocks on the market its really hard to make a generalization about whether one would track a thumper or not. Only thing I always would look at - how much flare potential in the ball? A pin-in configuration with a very high flare potential ball would red flag a high roll track player to stay away from pin-ins. (YMMV)
Most pro drillers will try and stay within your "safe zone" for drilling. I know my driller always wants me to stay above the finger line or at least very near the finger line with medium to high flare potential balls based on my fairly high track. - I guess one will not know unless one experiments with a sample drilling.
