An Impulsive Appraisal rotation can get you more items if RNG is good, but if you don't want RNG, the rotation I use guarantees at least 3 items on every 6 hit node (more if there's a +attempt proc):

Utmost Caution - Single Mind - Methodical Appraisal - Single Mind - Methodical Appraisal - Methodical Appraisal - Methodical Appraisal

Also requires 600 GP.
