I understand your point, I am hoping you are able to understand mine. Imagine a person who usually plays roundwounds and wants to try out some brighter flats. If someone calls TI Flats "floppy" others think of a roundwound string downtuned 2 whole steps. Now that yields a floppy string. So, that and the price premium one must often pay for TI Flats discourages anyone from trying these strings. So, they instead go out and buy a set of Chromes to avoid that floppiness. Now, the difference in feel between Chromes and roundwounds is very noticeable, especially on the G and D strings. But, TI Flats have more or less the same tension as a typical set of roundwounds. Thus, the term "floppy" has misled the end user into making a mistake that could have been avoided if "floppy" was better defined. This is true, because it happened to me.
As a favor to those coming here for information before making a purchase of TI Flats, I recommend we start telling people that TI Flats feel more or less like a set of roundwounds, while all other flatwound strings are usually more tight feeling under the fingers, some more some less. Compared to the thickest gauge Rotosound flats, or the Jamerson Labellas, TI Flats are going to feel "floppy." But compared to a set of roundwounds, there will be little difference. Doesn't that better define "floppy?"
