what is the difference between co-poly and poly?
I am so confused!!!!

Co-poly strings should feel softer and give more power.

Polyester Strings



Polyester strings show a fairly simple structure: they consist of a single polyester fiber with a thin coating. This type of construction is termed "monofilament". They come in different gauges (1.10-1.35mm) which enables you to choose among different elasticity/durability levels. Polyester strings are little elastic and feel quite stiff compared to nylon or multifilament strings, but on the other hand they provide significantly better durability, allowing for thinner gauges. Pure polyester strings like the Polystar Classic or the Kirschbaum Super Smash have one main downside: They tend to lose their tension quite quickly, so control decreases and the string feels dead after a short time of play. Thus polyester strings are only recommendable for players with high string consumption. For these players, polyester strings offer a great price/performance ratio.
During the past few years, tremendous effort has been put into the advancement of monofilament strings and the elimination of their major weaknesses (tension loss and lack of elasticity). Luxilon has specialized in this string category. More and more polyester blends (co-polyester), mixed with a number of other materials like PEEK, carbon or metallic fibers, are being developed to modify the playing characteristics. Almost every manufacturer carries such strings in their program today.
Examples: Luxilon Big Banger Alu Power, Kirschbaum Touch Turbo, Signum Pro Poly-Plasma, Polyfibre Poly-Hightec, Head Ultra Tour.

If you don't feel like trying Duralast, CyberFlash, SPPP, Alu 16, and Cyber Blue (for your own experimentations, of course,) then I would suggest sticking to Prince Syn. Gut 17. :shock:

The next generation polyester type string in the market today is now blended with other materials to solve a lot of the disadvantages that the old poly string has. The fact that the polyester is blended with other materials prompted people to give it a new name: "co-poly".

Co-polys have improved attributes over the traditional polys like more comfort (softer string), better tension stability, longer elasticity.

To add to the list of names of some of the new co-polys given in the example of the StringForum.net article, a couple of other brands also worth mentioning are TopSpin (Cyberflash, Poly Polar), and WeissCannon (SilverString, Match Power, etc).

Basically, by mixing polyester with different materials the attributes of the string is changed.
Poly strings are stiffer, low powered and are prone to a lot of tension loss.
Co-Poly strings have "added ingredients" which allow the string to be more elastic.
when compared to normal poly strings, they are softer, higher powered and show very good tension stability

edit: i took to long to reply. oops :p

Just to chime in, a co-poly doesn't necessarily need to contain ANY component of polyester at all! the "poly" in co-poly is polymer, not polyester, to be very anal. (This is a really minor point, and they are used interchangeably)

Oh noes diredesire, you've made it even more confusing!! :D

All copolys contain some percentage of polyester.

lol right now i use full pro supex premier ace (co-poly?) the stiffest strings i played with so far, so once i get rid of these i thinking of blending them, cuz i get NO feel at all.

Premier Ace is one of the stiffer polys out there and plays more like a traditional polyester. Big Ace is a co-poly though and plays quite soft.

i did full with these, and it was a big @ss mistake, im just going to cut these and try to soften up by blending them with synthetic gut.

BTW how is the big ace in 17L. im still debating on which gauge.

All copolys contain some percentage of polyester.

I think in general this is true, but wouldn't an isospeed string constructed of polyolefin ribbons fall under this category?

I guess it doesn't really matter what the strict definition is, I think we all have a certain idea of what "poly/copoly" strings are.

What should i the premier ace with? i want something that will soften these strings up for some feel.
