Theory: Components of spin in poly strings

These are my theories based on my personal experience using a bunch of different co polys. None of this is scientifically proven. Do you guys agree with my opinions? why or why not and is there anything you'd add to my list?

Poly strings produce more spin than synthetics.

Higher tension does not increase spin.

Textured (not shaped) polys produce more spin on topspin, slice and twist serves only, compared to the same string untextured. Texture doesn't help on groundstrokes because you are hitting through the ball much more compared to a spin serve where you're not hitting through the ball as much and therefore the extra "grab" helps.

Shaped polys produce more spin on all shots due to an edge cutting into the ball more than a round poly.

Snapback is a real component to spin.

Polys with a low string to string friction ratio will produce more spin compared to same poly with a higher friction ratio.

Lubricating polys with sprays or lubes can increase amount of spin, however it is not worth the health concerns from inhaling and coming into contact with chemicals.

The best safe lubricant is hand lotion which will increase spin, not as much as silicone sprays, armor all, ptfe etc but a noticeable amount.

Unless a proffesional who needs to use the same conditions every time, there is no need to restring your poly job when they lose tension.

You should restring after the string looses its elasticity and stops snapping back and becomes misaligned. This is usually at the same time that the poly looses tension but not always.

The stiffer the poly, the more the control and the less arm friendly and vice versa.

Softer polys generally loose tension faster than stiffer polys.

The thinner gauge the more spin potential because the ball will sink into the more open string pattern and vice versa.

The thicker the gauge the more control and vice versa.

Thinner gauge strings give more head heavy balance and vice versa.

Price has very little to do with quality of string.

Technique is a much bigger factor than string choice for spin.

String does play at least a 10% role in getting spin.

The more spin you hit with the faster you will wear down/break poly.

Most people should cut out polys before they break.

Most people should not use poly.

Some polys may work well with one racquet and bad with another.

Paying more than $12 is a waste for poly unless a pro or rich.

Luxilon alu and RPM Blast are by far the most overrated and overpriced strings on the market

People without there own stringer are reluctant to cut out polys due to the high cost of stringing

Fresh cheap poly is way better than old notched expensive poly

Poly plays best in the first 1-2 hours or less increasing as the level of play goes down

Prestretching poly takes away the awesome play of the first hour or so

If hybriding two polys a smooth round poly in the cross with a shaped poly in the mains will provide the greatest spin

Getting a string that works for you can improve your game significantly

1. Get stiff slick poly 200m
2. Work on technique.
3. Work on physicality and Racket head speed.

If you are having to seek for topspin in different shapes and strings, then you are not hitting with enough topspin anyway.

However, it is nice to get a setup that maximizes spin potential. Unf for all round playability+max spin, Gut/Poly is the way.

Poly strings produce more spin than synthetics.

Generally, yes.

Higher tension does not increase spin.

Correct, however, for some strings it lowers power which makes it easier to swing all out and produce spin without overhitting.

Textured (not shaped) polys produce more spin on topspin, slice and twist serves only, compared to the same string untextured. Texture doesn't help on groundstrokes because you are hitting through the ball much more compared to a spin serve where you're not hitting through the ball as much and therefore the extra "grab" helps.

I'd put it differently, as there also are textured strings with fairly good string movement. Textured strings have a higher launch angle than smooth strings because they grab the ball more. Some people like this, some people don't, it depends on the technique of the player.

Shaped polys produce more spin on all shots due to an edge cutting into the ball more than a round poly.

Disagree, it depends on the technique of the player IMO.

Snapback is a real component to spin.

And one of the most important.

Polys with a low string to string friction ratio will produce more spin compared to same poly with a higher friction ratio.

Ceteris paribus, quite likely, but we cannot know that as such a thin does not exist.

Lubricating polys with sprays or lubes can increase amount of spin, however it is not worth the health concerns from inhaling and coming into contact with chemicals.

That's news to me. You're spraying Silicone Spray or WD40 (or however they call it) onto your stringbed and rubbing it in, not spraying it into your face and inhaling it (also, they aren't toxic as far as I know). Oh and they do facilitate string movement, but only for a short while.

The best safe lubricant is hand lotion which will increase spin, not as much as silicone sprays, armor all, ptfe etc but a noticeable amount.

First time I hear that.

Unless a proffesional who needs to use the same conditions every time, there is no need to restring your poly job when they lose tension.

As long as they remain playable, yes. If they become dead though, you should definitely restring as dead poly stringjobs can cause arm problems.

You should restring after the string looses its elasticity and stops snapping back and becomes misaligned. This is usually at the same time that the poly looses tension but not always.

Yeah, same as what I wrote above.

The stiffer the poly, the more the control and the less arm friendly and vice versa.

Not necessarily. Solinco Outlast is fairly soft but offers tons of control. Stiffness and arm friendliness also is no linear as many factors come into play.

Softer polys generally loose tension faster than stiffer polys.

Generally, yes. However, newer co-polys are becoming better and better in this regard.

The thinner gauge the more spin potential because the ball will sink into the more open string pattern and vice versa.

Ceteris paribus, probably. Depends on the racquet and the player I would say though.

The thicker the gauge the more control and vice versa.

Disagree. There are strings where the thinner gauge offers more control.

Thinner gauge strings give more head heavy balance and vice versa.

No. Thinner gauge strings are lighter and thus add less weight to the head, so the racquet is more head light.

Price has very little to do with quality of string.

Indeed.

Technique is a much bigger factor than string choice for spin.

Bullseye.

String does play at least a 10% role in getting spin.

Not sure about introducing a number here, but strings do play a role.

The more spin you hit with the faster you will wear down/break poly.

Generally, yes.

Most people should cut out polys before they break.

BIG YES!

Most people should not use poly.

More accurately: beginners and intermediates should not use poly, but syn gut and/or multis.

Some polys may work well with one racquet and bad with another.

Very true, but it also depends on the player.

Paying more than $12 is a waste for poly unless a pro or rich.

That's subjective, though I generally agree.

Luxilon alu and RPM Blast are by far the most overrated and overpriced strings on the market

IMO yes, but some/many will disagree.

People without there own stringer are reluctant to cut out polys due to the high cost of stringing

No. Most are just unaware of the need to cut out poly when it's dead.

Fresh cheap poly is way better than old notched expensive poly

Not sure about this one. Depends big time on the polys (there are some pretty crappy strings out there).

Poly plays best in the first 1-2 hours or less increasing as the level of play goes down

Depends on the string. Some play best in the first few hours, some longer, others less. At some point you will feel a playability drop off though, that is true.

Prestretching poly takes away the awesome play of the first hour or so

Depends.

If hybriding two polys a smooth round poly in the cross with a shaped poly in the mains will provide the greatest spin

Not necessarily.

Getting a string that works for you can improve your game significantly

It can improve your game, but not significantly (unless you were playing with absolute crap before).

My thoughts:
Yes on people using poly too long... I know a lot of people that keep poly setups in their racquets as long as they would keep any other setup, which is not the way to go-- these people really shouldn't even be using poly in the first place.

As far as texture, I disagree. I think that textured polys don't really get that much more spin... mainly that they break quickly because the string's edges wear each other out (the friction in a full bed leads to the string breaking early)

I think cost is irrelevant too... there's a lot of polys, good and bad, and they come in all price ranges.
