The drawback to cross drilled is there tendancy to develop hairline cracks. Rule of thumb is once the cracks link one hole to another, the rotor is done. Slotted rotors don't behave this way and would likely be a better choice for your needs.

People don't re-surface rotors much anymore.

Also consider that a change of brake pad compound and brake fluid bleeding can have a greater impact on braking than simply changing the rotor.
