no, I don't know them, i prefer perfect round string, all I could test and compare personally for about 3 months was:
lux BBO alu power Vs weiss scorpion
and PP concept Vs weiss scorpion.
my balance sheet is:
for me, and that only engages me, but at the club, we were at least 6 players out of 10 between 5.0 and 6.0 to find that:
scorpion more comfortable than alu, largely better for the tension stability, as well for the control and the power.
that between scorpion and concept there are much less differences than between scorpion and aluminum BBO power.
once admitted this, out of the 10 test players, that two could take luxilon against scorpion, if one did not take into account the price of alu. because the famous special feeling of luxilon, but for the rest, there were no big differences between alu and scorpion flagrant in favor of alu.
that none would consider taking alu facing scorpion if we consider the price of weiss facing luxilon, and finally, none made a noticeable and glaring difference between weiss and PP.
finally, that if we consider the price, nobody would take neither luxilon nor weiss for a season.
finally, when asked to choose between a reel of luxilon or two reel of concept, everyone took two of concept.
Finally, knowing that weiss was one of the designers of luxilon, we can doubt that a little of the luxilon technology is present at weiss cannon?
strangely, weiss scorpion and PP concept exist in exactly the same gauges.
1.22mm, 1.28mm and 1.33mm (the 1.22 and 1.33mm are quite rare in poly).
PP concept exists in .. 1.22mm, 1.28mm and 1.33mm. amazing? I do not think so.
finally, to conclude, at my club, where there are about 350 members, there must be 4 to 5 players who use luxilon alu power in full bed. 2 people aged 55-60, who play 4.0 I think. or less? who never break their strings and who stop playing because of TE every month, two 15 year olds, who play with ultra light frames and luxilon, and the tennis teacher, who uses a babolat drive, and luxilon at 26kg, which never breaks, and who thinks that he has understood everything in tennis, since luxilon is the best of strings.
