What are there gouging issues exactly ? On our 6 LTs we have no sign of gouges as I understand it. We have streaks visible on the FEP layer but have not noticed any change in print quality due to those, and it was asked on the forum and confirmed it should not be an issue.
Now I’m not saying the LTs are perfect, these streaks should ideally not b present and there are gluing issues exacerbated by the fact that the tanks are used a lot mote than the standard ones. But we’re happy enough with them that we don’t plan on buying standard tanks anymore.
As for the film being more fragile I agree. It is more susceptible to being deformed by applying pressure on it and any large print failure is likely to lead to visible marks on the film. It’s also much more sensitive to cleaning with the spatula. We rarely get print failures though, if ever, and we’re careful when manipulating the tank so that’s really more something to be mindful of rather than an issue.
