I appreciate all the feedback everyone. I got an email back from Kifaru and they recommended a medium belt. That surprised me from the advice on here so I called and talked to a different person and they recommended the small. For the tiebreaker I texted Aaron Snyder and he said small. Based on that and the advice on here I am going with the small.
For the record, they emailed me back a few times pretty quickly and answered the phone when I called this week. I just had bad timing last week I guess. Aaron's phone went straight to voicemail, which was full, but when I texted he texted me back within 5 minutes. Great responses.
In the end I am going with ranger green 26" duplex lite with small straps and small belt, ranger green hoodlum, large belt pouch to run on top of hoodlum, gun bearer to run on right side, and gen 1 water bottle pouch and mini belt pouch on left. Can't wait to get it!
