DR Flats compared to Sadowsky Flats, tension-wise

I've tried both, on a Fender P. The DRs are definately close to the Sadowsky SBF45 (045-105) in tension. I would say maybe even a bit tighter feel, i.e. less flexible.

Soundwise I found the DRs (I tried two sets - both new) to be duller than the Sads, and also more uneven sound from string to string, even after breaking in. The Sadowskys are more articulate, very even feel and sound from string to string, and (it must be said) are my favorite flatwound string. YMMV, etc

If I were you, I would try the Sadowskys in Light gauge, 040-100, since you like a bit of flexibility. They are higher tension than TI flats, and a bit lower tension than LaBella 760FL, if that helps.

 

I have no personal experience with the DR Flats, but I 100% agree with what @Klonk said about the Sadowsky.

The 40-100 set to me has an ideal balance between being easy enough for my left hand and being stiff enough not to go all wimpy under my plucking fingers when I dig in. The string-to-string balance is also excellent both in terms of tone and tension, almost right out of the package. (Not like some flats that take six months to settle and balance out.)

You won't find many on ebay IME, but yes, check With Jason, or buy directly from Sadowsky.

I get what you mean by "scarce" because even Sadowsky themselves have been out-of-stock on these for more than a month at a time.

Hope you like them!
