Hi All, I emailed Carrie yesterday and it seems Aero shoulders and p2p are static, all other things can be modified. Size wise I easily fit Schott 654 medium (p2p 21) and I need shoulders 19". Not able to find any aero pattern with this config. There are 22+ p2p with 19" shoulders which will make jacket too baggy on back and chest. I am looking for J100 style, are there any jacket makers similar to aero quality with MTM? Simmons bilt does full MTM for $400 extra, thats one option I am thinking of. I saw a FS post a while back for Simmons bilt j100 44 in shinki which was similar to my measurements , not sure it was custom or stock sizing.
