the luxilons are a little harsher than most polys...i've heard the flouro is a little softer, but still like the other luxilons, they loose tension fairly quickly...i would give the msv focus hex, Signum pro hyperion, technifibre black code, or weiss cannon silver string a try...you can hybrid them with a soft multi -- there are sooo many other good polys out there other than the luxilons...good luck!
I agree.
Luxilon strings and Pro Hurricane Tour are all poly's of the older generation and they die very fast and are harsh on the arm, they feel boardy as soon as they dies and loose all of their alreasy limited elasticity.
The Luxilon Fluoro and M2 are Luxilons try at producing a more arm friendly poly alternative, but they still die very fast and have very poor tension maintenance and weak tension stability.
I would recommend you to try some of the new softer CoPoly 4.th generation alternatives, which have EXCELLLENT tension maintenance and fantastic tenstion stability.
WeisCannon SuperTwist, Tecnifibre Black Code, MSV FOCUS HEX and my two current overall favorites:
Signum Pro Hyperion - nice power, good spin, excellent tension retention, good feel and very nice black color
Signum Pro Tornado - nice spin, good comfort, great feel and great tenaion retention and very nice black color.
