Pretty sure that is a Warwick, not a Protechsport. I can't find a picture on his website that shows all of the molds but all of his masks seem to be more rounded(the shells, not just the vents).
I did a head mold for my Pro's Choice it wasn't that bad. My wife, gf or fiance at the time, helped me with it and had fun with it. It's really not as hard or scary as it may seem haha.
I was so upset when I found out he was retiring. I wanted one of his masks so badly. We emailed quite a lot when he was more active on the GSBB. When he was available I didn't have the cash. Then when I had the cash he was backed up so I went with Pro's Choice. Unfortunately I think that decision damaged the relationship I had made between Ed and myself. Something I didn't intend to do. It is what it is though.
