it is a while back since i played the regular alu (am going to test soon the alu power rough), but i liked then the 1.20 kirschbaum competition more than alu for instance. from that one i have moved on to the mantis power poly, which up to now is still my go-to string. but i find it a little bit awkward that you say the l-tec plays like alu while pvaudio said that it played like polyfibre black venom. that would be quite at the opposite sides of the spectrum in my view. or i have messed up the particular hybrids you are talking about and then it is all my fault.
