Alpha Viper MXT Review
Reprinted with permission of the
United States Racquet Stringer's Association
Viper MXT is Alphas newest premium solid core string. It offers exceptional resiliency while maintaining desired tension. Manufactured in Japan, Viper MXT has a specially designed speckled coating that provides optimum feel and durability by reducing friction between strings..
The two coils tested measured 397. Diameter ranged from 1.29 mm to 1.31 mm. Stringbed stiffness of 78 RDC units was recorded immediately after stringing at 60 pounds in a Wilson Pro Staff 6.1 95 (16 x 18 pattern) on a continuous pull machine. After 24 hours (no playing), stringbed stiffness measured 72 units, representing a 7.70% tension loss. Our control string, Prince Synthetic Gut Original Gold 16, measured 80 RDC units immediately after stringing and 73 RDC units after 24 hours, representing a 8.75% tension loss.
Tested for five weeks by 27 USRSA playtesters with NTRP ratings from 4.0 to 6.0.
Viper MXT 16 is very easy to install. It doesnt recoil like some strings and has minimal silicone coating, making handling and clamping easier. Even without a slick coating, cross strings weave smoothly without any burning or notching. Knots tie easily and cinch up nicely. No problems here.
Viper MXT 16 started out playing firm and crisp but quickly settled into a comfortable and predictable string. It provided sufficient power and very good control. The non-slick surface kept string movement (and notching) to a minimum, even with spin shots, although some discoloration occurred within a few hours of play. Touch shots were about average as was tension maintenance; we recorded 18% tension loss over two weeks of regular play. There were seven reports of breakage after 4, 6, 8, 12 (twice), 15 and 17 hours of play. Fifteen respondents (58%) indicated they would carry the string in their shops. Responses on expected price ranged from (11) $2$4.99, (13) $5$7.99, (2) $8$11.99.
Viper MXT 16 provides a predictable, comfortable response and adequate power, but does not perform with any discernable wow factor to separate it from other synthetic gut strings. A good workhorse but no stallion, its a solid performer for a $6.45 string.

(The string most commonly
used is in parentheses)
Nice 16 gauge string, but theres no particular advantage compared to other strings on the market. 4.5 baseline player with heavy spin using a Head Radical Twin Tube MS strung at 57 lbs. (Gamma Pro 17L)
Feels stiff to the hand, but plays spongy with good shock absorbency. Below average control. 4.5 all court player using a Dunlop Max Superlong +1.00 strung at 55 lbs. (Dunlop Syn Gut 17)
A comfortable string to install and play with. I would recommend this to players who like soft string and people with arm problems. 5.0 serve & volley player using a Prince Precision 690 strung at 53 lbs. (Dunlop MaxComfort 16)
Nice feel and comfort. Great control and power. 4.0 all court player using a Yonex Cyborg 2700 strung at 55 lbs. (Gosen SuperTec Gut 16)
I found the string to be somewhat stiff during stringing, but this didnt present a problem. I noticed a number of blotches and discolored spots, which makes me wonder about the quality. 5.0 baseline player with moderate spin using a Prince Extender Blast MS strung at 62 lbs. (Velociti 17)
This is a very durable string suitable for todays oversize widebodies. 5.0 all court player using a Wilson Pro Staff 6.1 95 strung at 60 lbs. (Prince Syn Gut 17)
Great string with terrific feel and playability. 5.0 all court player using a Prince Precision Spectrum MP strung at 62 lbs. (Prince Syn Gut 17)
Really enjoyed playing with this string. Should be a good string with durability for heavy spin players. 4.5 touch player using a Prince Precision 730 strung at 57 lbs. (Gamma TNT 16)
Surprising durability in a very playable synthetic string. Felt a bit stiff at first, but after a couple of hours the string softened and felt great. 5.0 all court player using a Wilson Hammer 5.5 95 strung at 58 lbs. (Wilson Synthetic Gut Xtreme 16)
Just an average string, nothing unique. 5.0 all court player using a Yamaha Secret 04 strung at 58/54 lbs. (Ashaway Crossfire II)
I would recommend this to the player that likes a lot of touch and feel. 5.0 baseline player with heavy spin using a Prince Precision 720 strung at 58 lbs. (Prince or Wilson Syn Gut 17)
String felt hard and stiff. I felt quite a bit of shock. 5.5 all court player using a Wilson Pro Staff 4.2 95 strung at 60 lbs. (Prince or Wilson Syn Gut 17)
This string felt stiff while uncoiling and stringing. Suitable for long oversize and super oversize frames. Moderate power players will enjoy this string. Outstanding tension maintenance. Even though it is a stiff string, it didnt play harshly. I would recommend this string. 4.0 all court player using a Weed Zone Plus strung at 65 lbs. (Gamma TNT Pro Plus 17)
This was a pretty good string. I wouldnt consider it a soft string, but it offered good feel. I dont think its terribly powerful, but it maintains tension great and would suit widebody racquets. 5.5 serve & volley player using a Dunlop Classic Pro strung at 57 lbs. (TOA Silencer 17 or Dunlop Syn Gut 17)
