kokoda trail

Hi, I am so confused about which tour company to go with to do the kokada trail/track. I would love feedback from people who have done it and who they went with. Cost isn't too much of an issue if the tour is worth it
Planning to go in JUly ( is this the best time?)
I am pretty fit but would people recomend the longer trip ( 12 days) or shorter (9 days).
thanks in advance for any info!
