On this board Big Banger Alu Power is "the man". Every other thread is about how wonderful it is. As for Prince Syn Gut Duraflex, forgeddaboudit you loser. But check out USRSA website for their string tests. Alu Power scored very low indeed (as you might expect from a string which seems to have a lot in common with piano wire). I particularly liked the bit where it tells you to watch out while stringing in case you fatally stab yourself with it. And Duraflex is the all time test winner, or was until the latest Wilson NXT came along. Why?
