I’ve used silver, ice blue and lime colors of Alu and have a few packs of black on order and will string up either later this week or next. I dig dead feeling polys so I played ice blue Alu for years. Am probably going to go back to it, actually.
I always felt, from most to least powerful, the range was: Lime - Silver - Ice Blue
I’ll update the thread with my impressions of the black (which I’m guessing will be as dead or more dead than the ice blue).
