I'm pretty sure there is a reach version somewhere, but I can't seem to find it now that I'm looking. I swear I had one, but it may have been h3.
11 Helmets in two weeks in pep, that's a lot of work. I believe if you make a mold you can cast in Rondo (Resin+Bondo slurry), I think I saw Sean Bradley or someone do it back in the day. Could be wrong, but it might be something to look into. Somewhere there is (or sued to be) some talk about using the silicone caulk from the hardware store to make molds, but I don't think it worked very well. Again, its been a long time, I could be remembering wrong.
