I'm also not a fan for the high-pitched helmets, but you know at the end of the day it's what HIK wants so I don't dispute it. Also youre gonna expect some volume issues since your recieving audio files from a number of sources and not one recording studio (I recorded mine from a cheap & nasty internet mic all the way from the UK).
You know, Gruff Fokker took a little getting used to but I knew what I was expecting via Hik's Macross Zero dub. I think it actually suits him here since its a hardcore Roy for a hardcore animation (Especially his death scene).
OK technical issues aside, we have to remember the project is STILL A WORK IN PROGRESS. If I know Hik he'll be tinkering away at the project untill he's satisfied with it for the HiQ (Nice TF reference there!).
Anyway, that's my two cents.
