Verdict: apart from the TSG Evolution that had a really horrible fit, the other 4 helmets were fitting well, but the Bern Macon was really the best of them all, and the only one below 21cm outer width = the lowest visual profile. So, this is the one I am keeping and it's really close to perfect. Also, the strap material of the Bern is better than the rest. While it's probably Nylon like the others, the Bern straps are somehow more heavyweight and with a smoother finish, simply feels nicer.
Added Bell Local and TSG Evolution.
