Anyone rocking Rotosound RB45's

I want to ask those who use these strings how they like them.

Im thinking of getting them because they are dirt cheap and im able to get bulk discount on them. So far Ive used the classic RS66LD, roto flats, Labella flats and ernie ball hybrid slinkies.

For me LaBella is big no in my book, cause two packages from the two Ive ordered had defective strings, hence why I use rotosound monel flats. But Im still messing around with roundwound strings.

I had the Ernies but that was early on when I wasnt able to tell much on how they sounded cuz my ear wasnt trained well and I had bad amp. And after that Ive only used the RS66LD. Thats why I want to ask what do yall think about them, what do they sound like, how long will the "stable" period after first break in last.

Thanks!
