I've been rather successful at using another rotation I found on these boards.

I've got 616 Gathering, and 652 Perception. I was mostly doing this with just over 600 GP, but I've since added enough GP materia that with a cheap food I'm over 650 GP.

One swing to reveal.
Optional : Sharp Vision/Field Mastery. Only if 650+ GP at the start and need the boost to gathering rate.
Discerning Eye, Impulsive Appraisal. 155 Collectability.
If proc, then Single Mind, Impulsive Appraisal. If no proc, then Discerning Eye, Impulsive Appraisal. 155 Collectability, 310 total.
If proc, then Single Mind, Methodical Appraisal. If no proc, then Discerning Eye, Methodical Appraisal. 172 Collectability, 482 total.

This gets you two collects, without any luck in the procs. Each proc gets you one more collect, up to four total collects.
