Well...in theory, it would be a good choice, but it depends on HOW broken down the heads are. While it is a pearl ball, many people forget that particle pearls are still PARTICLE BALLS. I find myself forgetting this from time to time as well. I personally am a big fan of particle pearls, I have thrown a few (Ebonite Afterburner (retired), Diesel Particle Pearl (for sale), and a Track EMB XF (still throw)) and liked them all at one point or another. The typical reaction i've gotten out of particle pearls is natural length and smooth/arcy backend movements. Depending on the ball, i've found that this would either help smooth out screaming backends (my XF) or cut through carrydown (my Diesel Particle Pearl).
As mentioned before, depending on how broken down the heads are, this might be a good choice. If you are throwing a particle ball and need a little more length, a good step down would be a particle pearl drilled for a little bit of length. However, if everything is checking up early, particle pearl is NOT the way to go, a VERY weak reactive pearl or perhaps even urethane is the way to go there. Obviously urethane won't cut through oil, but you have to take the lesser of two evils if the heads really are that nasty.
Hope this helps!
