Custom clicking is not only going to cost more but take way more time. I'm guessing FG doesn't operate with a huge amount of leather stock, and keeping two standards of clicking would just be super confusing and turn into two tiers of leather quality rather than "guaranteed good leather" and "roll the dice with veins". Since the easiest way to have that pricing model is to just separate out the leather from the start. You'll end up with "pay for good leather" and "pay less for worse leather". In that case, why not just up the standard clicking and raise prices? Because that's not what FG wants to do. They competitive edge is the MTM option at such a low cost and their patterns.
Yeah the veins look awful and that should be something that's talked about as a quality issue, but it's not something that really unexpected IMO. $800 for a MTM, MTO full leather jacket, something has to give. Personally, I think the veininess is one of the best ways to do it. It's not consistent like shipping out every jacket with shit hardware or something, not all are duds, and some less so than others. Plus, buying calf, goat, or suede makes it a non-issue.
