Have you ever noticed the pro’s who use polyester strings in the mains and natural gut strings in the crosses? Andy Murray, Alexander Zverev, Tommy Paul use this hybrid. Why do they do this? I personally think it’s to save their arms. They keep the performance and feel from their favorite poly in the mains...

Considered by many to be the crem da la crem of polyesters. Used by so many professionals, it is THE standard of top tier polyester tennis strings. So many people consider this to have the perfect amount of stiffness and power. It also loses playability THE FASTEST. Average playability is around 1-4 hours (depending on...

Considered by many to be the crem da la crem of polyesters. Used by so many professionals, it is THE standard of top tier polyester tennis strings.

So many companies have released a “soft” variant of their poly string because they are realizing that their strings are destroying arms. But the “soft” versions aren’t truly soft. They’re honestly worse. They hold tension worse and they go dead faster. However Solinco’s soft variant of their famed Hyper G is, in my opinion, JUST...

Solinco is an American company that is making waves in NCAA collegiate and also professional tennis. The Solinco strings I’ve chosen are pretty darn amazing for spin, tension maintenance and longevity. Yes, it lasts just a little longer than earlier generation polyesters (10-20 hours vs 1-4 hours) which, I think, makes it pretty special. Plus...

Poly is infamous for 2 things: extreme stiffness losing tension Then came along Isospeed Cream! They also stopped calling it poly and gave it a new name: co-poly. That’s because there were so many additional ingredients they couldn’t simply call it poly. I dunno, I’m not a chemical engineer. Cream was one of the first...

It’s still one of the “softest” polyesters out there, Head Sonic Pro 16g has proven to be a go-to choice for those who want the polyester characteristics minus the harshness. It has the stiffness of a nylon “synthetic gut” (most polyesters are MUCH stiffer) and maintains tension and playability quite well throughout it’s lifespan (polyesters...

This is the cheapest and possibly the best value polyester of all time. This particular poly is 5 sided and plays VERY similar to a lot of 2nd generation polyesters but because it isn’t sold by a major manufacturer, they don’t have the same markups. I honestly think it’s all made in the same factory....

Tried and true since the 80s and 90s Gosen continues to produce some of the best “synthetic gut” strings. I simply call them nylon because it’s the exact material they are made. Manufacturers called it “synthetic gut” because it sounded more sexy.  A perfect mix of crispness and power, these strings are a really good...

Can you really improve on the OG of tennis string? Yes, you DEFINITELY can and it’s some amazing stuff. So just think of all the amazing properties of natural gut (soft, powerful, comfortable and playable until it breaks) without ANY of the problems (swells and breaks with moisture, frays quickly). Yes, my head is dunked...

This black PEEK monofilament is the newer version of the PEEK family. Since it is a monofilament, it is smooth and slick and is amazing for spin. This color behaves slightly more like polyester than the natural colored PEEK. Meaning it plays slightly firmer and is a little more dynamic so I think it imparts...

This is the string that started my whole journey. I was in the middle of multiple arm injuries and I needed to find a string setup that didn’t cause more injuries. During my quest I discovered chatter about a string that is as soft as natural gut but as slick as polyester. I had to...

A single extruded monofilament, Fluorocarbon is more abrasion resistant than standard nylon monofilament of the same diameter. It is almost as soft as natural gut and has just as much power. Plus, while the sun’s harsh ultraviolet rays weaken nylon over time, fluorocarbon shrugs off UV with no ill-effects. It is also known by the...

I think when they started manufacturing multifilaments to immitate natural gut, there were probably some other chemists and structural engineers who were like, let’s go in the OPPOSITE direction. Why? Why not! In these modern tennis times of spin/polyester/RPMS I think it finally makes sense. Racquets are so powerful now to compensate for the low...

If you can manufacture ANY property into a string, why not infuse such popular poly properties into a multifilament? So this company put poly fibers into their multifilament to create a really interesting string. It’s soft like a multifilament but has similar stretch and low power properties of a poly. I personally think it’s brilliant.

Not soft and mushy like some multifilaments. This one is crisp and powerful. Like how some of us wish natural gut was. This multifilament is actually a little stiff by comparison but that also makes it an easier transition if you’re coming from the world of polys. String manufacturers have been trying to imitate the...

I might be the only stringer who still believes there is a place for polyolefin strings. What is it? Well technically it’s still a plastic just like nylon and polyester, however Polyolefin is almost as soft as natural gut but has limited stretch like polyester.  Not all multifilaments are created equal. This one happens to...

Also known as “synthetic gut”. I think this is the most misleading description of a string, ever. It is NOTHING like gut. It’s stiff and doesn’t give. It’s basically nylon. Most synthetic strings actually are made of nylon. But it’s much sexier to call it “synthetic gut” than “nylon”. Having said that, nothing is wrong...

You’ve seen the words, “Synthetic gut” used for a string. It’s a sexy term for something that is basically made of nylon. Nylon=plastic. Plastic ≠ gut. Gut is made of stretchy cow intestine. So is synthetic gut a synthetic “gut”? You be the judge. But the string (whatever you want to call it) is still...

Kevlar is the brand name but the material is called Aramid. They are fibers that have more tensile strength than steel. Meaning they don’t break when they are stretched. It’s the same stuff they put into bulletproof vests.
