Wow, you weren't kidding. I went straight for the 4d's and i guess that was a mistake, with the pgd pads in the thing fits exactly like I want it to.
@Anb618 , if you didn't try this be sure to before you send the pgd back, the amount of difference doesn't seem like it should be possible, apparently it is though. Since you're just wanting ballistic protection it's unquestionably a better choice than the chinese made HHV. If it's still a no go maybe look at a Galvion Viper a3 high cut, one of those caught a .223 for a cop in the orlando night club shooting (don't buy expecting that obviously, way beyond rating).
I meant is there like a rule of thumb in terms of actual measurement, i.e. if you've got 1/2" of space you're good, but if that comes down to 1/4" then even though you can get the helmet on your head comfortably it is now considered too small.

Since apparently I should ask before spending my money on upgrades, seeing as I now have a set of 4d deluxe pads to sell, do y'all think an ops-core h-nape would be worth while? The boa seems to do a good job but feels a bit bulky, and the strap->chin pocket design looks like it'd do a better job on the OC.
@WALLYBOB , did you ever get the fit sorted out on the wilcox shroud? how?
