Curt Mangan Round Core vs DR Sunbeams

[wguitar]

Happy Thanksgiving AGF friends !

Wondering if anyone has used the Curt Mangan round core strings (80/20 or PB). If so, how would you described them. How do they compare in playability to DR Sunbeams (which I find to be very comfortable to play). I like DR Sunbeams but would like to try a round core 80/20 for tone experimentation.

Thanks!
