Have SIT Power Flats Changed?

[Mikhail1]

Okay, I tried the search function and didn't find what I was looking for but I remember somebody saying in a post that these strings have changed. I like SIT's, particularly the Silencers, and have been wanting to try a set of flats. I DO NOT like ground wounds which I understand the Power Flats to be but in a post, somebody said that they are now true flats so this perked up my interest. Can anybody confirm this?

They have changed.

They used to be available in both 45-100 and 50-105 gauges, but now they only offer 45-105. Some 50-105 are remaining in their inventory.

Now the new ones do not have a specific description from them yet but they do not seem to be half rounds to me, more like a true flatwound.
