I emailed their customer service department and got this prompt response. The review that they sent me to is quite good.

Hi James:

JB is using Monsoon in both Episode 7 and 8. Tony Almeida is also wearing a black Monsoon in eposide 7

Sitka/Kodiak are our best and most comfortable Gearslingers to date. The Sitka is smaller than the Falcon. The Kodiak is larger than Falcon but smaller than Monsoon.
