OPA1622: Parallel Operation

Part Number: OPA1622
Other Parts Discussed in Thread: INA1620, TINA-TI

Has anyone ever tried the OPA1622 in parallel operation (to increase output current)? Is there by chance an app note for this configuration?

Would you say the 1622 is better suited in parallel as a (1) shared input topology, or (2) leader-follower topology? 

What would be the quickest way to test 1622 parallel configurations in TINA or PSpice? Does T/I have a TINA/Spice reference build for the OPA1622?
