Comments: I played with NRG due to elbow pain. It was super great, but the durability was bad. (For me, it
lasted about 8-10 sets). Duramix was less sensitive than NRG, but lasted noticeably longer. A much better value.

Comments: Duramix is an unbelievable string -- it has all the best characteristics of a multifilament string with
rigidity in feel of a poly but without being harsh like a standard poly! That is not to say that Duramix is mushy or stiff but
different! Its like the best of both worlds, you can have your cake and eat it too with this string! Bon appetite!

Comments: Compared to Kirshbaum Pro Line 2, or Babolat RPM Blast, this string is much smoother on my
still has a lot of spin potential. It is more durable than any multi string, but not as durable as the two other tested poly
Still, I enjoy them a lot. Highly recommended for poly string addicts that have arm issues.

Comments: I've been using this string on my HEAD MicroGEL Prestige MID (58M55X) since late September
and just found out here that it's a polyester mix. If I had known this was the case, I would have asked for another brand
Gut. But surprisingly these string last much much longer (within the same time period of constant play) than my "ole
Prince SynGut DF16 with about the same playability and finesse. I play on hard court and am a lefty flat hitter, other spin
top-spin. The outer coating is worn at the sweetspot, but it barely rubs into each other and still has allot of life left on them.
does explains the mild Tennis Elbow I've been experiencing (falsely attributed to using regular and soft PENN balls for hard
play), but not as serious as my brief stint with ALU as I'm able to recover to play the next day. I'll drop the tension further
how it goes. Don't care much for the "HD" naming, but the results speak volumes. Color me impressed.

Comments: I love this string. It has great spin and power but still able to have great touch! I have had a
injury and it is very soft on it! the only downfall is it broke with in 5 hrs! I am a national and southern junior player.

Comments: Just to update the comment I made bellow a couple weeks ago. I experienced some mild elbow
irritation either because I played a few days with wet heavy balls due to wet conditions (Fl 90% plus humidity) or my string
was a bit too high. Anyway, I lowered my main(BB ori 16) down to 50 lbs and my cross (tec duramix) to 46 lbs and the
result is just
awesome. Ball bite, spin, power are a whole lot better, and amazingly there is still plenty of control. Best of all, my elbow
get better. Give this duramix a try. Racquet used in: K 6.1 tour 90.

Comments: I have been looking so long for strings to use as crosses with BB original 16 as mains on my K 6.1
90 and I just found it. I just bought a reel of duramix 16 and I was very please with. I strung my mains 53 lbs and my
lbs and it turned out great. The power, control, and spin are all there. The soft sticky like texture of the duramix help hold
mains from moving around enhancing spin and control. Backhand slices and volleys become so easy and I can put the ball
with confidence. I can serve with a lot more precision down the T, slice and kick serves out wide become easier too. I have
playing with it for over a week now and the duramix still hold tension very good. It only has some light notches where it
contact with the mains. I had NXT and Isospeed control 16 as cross strings before but NXT is only very good about less
week and things go down hill after that. The NXT can't hold the mains in place so the control is not there. It eventually frays
breaks quickly. The Iso speed control 16 is OK. It just does not have any power and it has a death feel. Durability is a little
better than NXT and like NXT; it can't hold the mains from moving around.
