I would go with 3-2 zone and low post. My reasoning is that your best players seem to mostly be inside players (Power Forwards), so you will be most effective on the inside game. You don't seem to have a true Center, so I would assume you don't have anyone with spectacular rebounding to play center and snatch all the rebounds in a 1-3-1, so 3-2 is more useful so you have 2 players under the rim after the opponent shoots
