I listened to Mo mention he puts tape on the pin to see how the ball rolls. Would this be better then tape on the pap? It would be easier to see when the ball is getting in its roll to the pocket.

Tape on pin purportedly shows that with shorter pin-pap, the core will "lean" toward the rack as the ball hooks.

There are multiple locations for tracer tapes and each would show you something different.
Such as a tracer tape running from the pap toward the fingers for counting revs and a one you placed above the fingers to watch the roll into the pins. (like the old AMF Magic line with the 3 white dots above the fingers, that was a roll tracer built into the ball.)
You can see some different tracers being used here:

Here's a video that might help:

In this video clip you'll see the ball skid through the heads, flare up onto a second axis then roll into the pins on another axis.
When you understand what's going on you can make much more sense of what might, at first, appear to be a confused blur. Try to look only at the white dots placed on the ball.
1- In the first second, just after release and as as the ball skids through the heads, you'll see a steady piece of tape: the ball is rotating around the bowlers initial axis (the PAP, Positive Axis point)
2- After this, the axis will start to move, migrate, from the PAP towards the grip line and you'll see the second Axis settle down (if only briefly)
3- Finally, the ball will move off that axis immediately prior to rolling into the pocket for a perfect strike. Notice, at this point, that the ball has flared so much it is almost rolling over it's initial axis (first tape).
This shows about where the tracer tapes are placed.
