in regard of spin? in the mains? is that what you mean by sharper?
By sharper I mean strings like Dunlop Black Widow (7 sided profile), Polystar Turbo (star shaped profile) and alike. Alu Power Rough is successfully used as a cross string for natural gut, probably because "rough" texture on a harder surface actually reduces friction (it becomes less sticky or something).
