my regular string set up genises black magic 52 pounds tension racquet is POG 90
I strung the string at 52 pounds full set
Power: thought the string had good power on both ground strokes and serve
Feel: the string had a very soft feel for a poly unlike other luxilon strings and is also simular to the feel of luxilon savage.
Spin: string gave plenty of spin on serves and ground strokes both top spin and slices.
Control/durability: had very good control durability seemed good so far for about 14 hours of play.
tension: tension maintance was good felt a differnce in feel at about 12 hours of play
the 4G string is simular to the black magic same feel has a little more spin also has more power
liked this string a lot as far as feel and play ability did had difficulty stringing due to memory of string and kinked a lot, also wished it came in more colors aand probably carries a high price like most luxilon strings
