The derivative nature of the Oil Drum/Oil Rig, Fuel Cell/Batwolf, Hijinx/Antix stuff can be compared to the Twenty/Minute, Eye Jacket/Trenchcoat, XX/Juliet, Water Jacket/Racing Jacket, etc. styles of the past.
Except that those were smaller and more appropriate for other fitments, where as the new stuff is all large and shield design. There isn't a lot of variance for facial profiles with the new. I can wear every single unisex/men's piece being it BatWolf, Fuel Cell, Antix, Gascan, Hijinx, Oil Rig, Oil Drum, etc....I couldn't wear a minute of any variant ever, and XX was a very small fitment on me. So there are major differences in that area, but I agree they do tend to over saturate with one look or style...
As for OCP, unless I get some smoking deal, I am DONE!!! Too many times that not, I have had several weeks of wait time, and to me that is just unacceptable. Especially when I call weekly or even bi-weekly to get an update and just get told, "we are currently filling orders as they have come in" which translated means "I am a CSR and have no idea WTF is up with production and you are probably the 50th person today with the same complaint, have a nice day :)" response....It has just not been worth the headache. I have so badly wanted to order a custom holeshot, but waiting 3 months for a $125 pair of shades is beyond the limits, can't imagine waiting for almost $800!!! I will wait to test the waters as others share good info rather than the norm we have now...Maybe next year sometime...I hope with fingers crossed..
