What players say

Mixed 1 source

Dunlop Synthetic S-Gut 17 has no dedicated video or written reviews; the available data is customer feedback on Tennis Warehouse. Most recent reviewers use it as a cross string to soften a poly or co-poly main and call it durable and comfortable for the price, but older feedback is split between players who found it underpowered or quick to break and others who liked its spin and quality for a budget synthetic gut.

Best for

  • Cross string in a poly/co-poly hybrid
  • Budget-conscious stringers
  • Players wanting a softer feel than full poly
  • Moderate swingers, not big spin or power seekers

Pros

  • Several reviewers say it softens the feel of a poly or co-poly main when used as a cross
  • Called durable and good value by multiple Tennis Warehouse reviewers
  • One reviewer found it surprisingly spinny and not too stiff
  • Rated a cut above basic synthetic gut in build quality by at least one long-time user

Cons

  • One reviewer found it moved around too much as a main string in a 100 sq in frame
  • Power is rated low to underpowered by more than one reviewer
  • Durability reports vary, with one player breaking it after about 8-9 hours
  • No independent written or video reviews exist beyond retailer customer comments

Voices

I like that you get a durable but soft string for crosses to soften the feel

The string is great for the crosses in hybrids. It's durable with good feel

I originally purchased this string for use in my 100 square inch Aero Pro racquet, but it moved around too much

Tried the pink 17g in my Dunlop 4D Aerogel 200 Tour. It has surprisingly decent spin, not too stiff, but very underpowered

— Rob, Tennis Warehouse customer feedback, Web

I'm an average player (3.5-4.0). These strings broke after the 4th time on the court, about 8-9 hours of use.

— Tim, Tennis Warehouse customer feedback, Web

This synthetic gut string is on the better quality of synthetic guts. And at $3.99 a set, it isn't bad on price.
