rough

Hey all, as you can tell by now "rough" in tennis strings are very very very vague. I'm new to poly rough strings. I'm looking for the same "rough" as the "rough" in the TCS Rough. I just prefer this kind of "rough" over all the other "rough". What I'm not looking for are the shaped string...

Was hoping someone could tell me the difference, or their experience having played, between: Alu Power Alu Power Rough Alu Power Spin Alu Power Feel Alu Power Fluoro Alu Power Soft What is the goto Alu Power string? And why is it sometimes called Big Banger? Is that the previous naming for it...
