It's all good. I just wanted to add "contacting the vendor" as an option because it did not cross my mind when we spoke about it earlier.
I have had the same experience, though, in that I haven't heard much about +28 offsets. The good news is that there are some very knowledgeable members on the forum here that will be able to speak to that subject better than I can, and cover all the pros and cons that come with those numbers. I am curious about the range of offsets too, and the effect they would have on the overall appearance.
For the majority of threads that I read on this topic, people tend to go with +24.
