So the conclusion as i read is..
The upscale line is compatible with other lines besides TSK, but crossing should be avoided ?.
The upscale line is actually the (more or less) best line of caramels regarding the kinking ?.
Your saying that out-crossing is a good thing (even with my knowledge) i do agree, but only if the lines your working with are compatible correct ??, which they all are ??.
In the thread im referring to in my first post you have wrote about some crossing with the lines you mention in this thread..any updates ??.
