I have never ported a set myself, so I am a novice for sure. What concerned me right off the bat is what looked like a lot of untouched rough casting walls, which would mean they weren't touched.
Like I said, I'm not going off on the guy yet, I'm just trying to reconcile what I see vs. what I thought I bought. I'll be pleased as punch if these actually do flow well, as that's what I want and what I paid for!
