Also what I noticed, and it could just be me is that there's the tacticool guys on YT who run your regular IWB holsters. Like Warrior Poet, Tier 1 Concealed, Knockout Lights, etc...
Then there's the Phlster Enigma following who are made up of regular folk, like non in shape or tactical dudes. Like your grandma, women, fat guys, beta looking guys etc...I mean John Correa (Active Self Protection) isn't tacticool looking either like the T1C guys.
Same guys don't use wedges. So this shows the various different types of body types and the needs that aren't the same for everyone.
For some good info, check out the Phlster COncealment Workshop group on FB. There's lots of people sharing their XP and even the owners responding to most questions/post. Lots of pics and use the search function for specific. Like I searched Gym or Pregnant and found lots of post.
