the unfortunate thing with pepping is trial and error, the chaps on here and 405th have said sometimes you have to build original file size for helmets or armour to see where adjustments need to be made if too small or too big. The other thing if your patient enough during pep form is to cut the items down if it will not interfere with the detailing. The other thing I found is the helmet fitted in pep form, but because I didn't place any support inside when resinning, I used a heatgun to adjust the helmet for fitting. The guys have been really helpful with advice and tips, this is my first project, I've learnt alot and how to overcome bits for next time Hope this helps. Look forward to seeing your progress dude, keep us all posted
