I have seen that some string brands like luxilon recommend to 10% lower. Can anyone tell me what this means? lols I feel like such a noob

because Poly strings are so stiff compared to synthetic gut it is recommended that you string them at 10% less tension than you normally would get synthetic gut strung at

so, if I string at 62 normally with a synthetic gut string, would that mean I would string my poly at 52?

I believe it means 10% less than 62, not 10 lbs. lighter.

no, that's 10 lbs less.

divide 62 by 10 and then subtract that from 62.

so 62/10 = 6.2, 62-6.2 = 55.8 lbs. so 56lbs is the approximate.

Poly strings are for the most part much stiffer than syntehtics/natural gut.

Therefore, for one to get the same feel of the string bed with poly, compared to their synthetic, it is recommended to string looser.

and NO. You are not a noob.

I'd string Alu at 10% less than a regular poly. Not synthetic. Perhaps 15-20% lower than synthetic.

I used Luxilon B.B.Original and Rough version and now I'm using Signum P.P.Plasma 1,23. Producers suggest that you should string 10% less than normal you string... NOT TRUE FOR ME. I didn't do it and it's still good. It's difference between 57lbs and 52,7lbs. Well, it depends on individual preferations, but I won't string less 10% never ever

I don't have problems with that. Furthermore - there were researches and conclusions are that problems with arms are not caused by high tensions but it's basically from one's muscles structures and it depends on nature, so to speak. I've heard it from coach.

The ambient temperature might make a difference, also. As we(in the States) head toward cooler fall weather, that tension shift becomes more apparent, I believe. In hot weather, regular tension on the poly might feel OK and help guard against rapid tension loss(relatively) but the cooler weather would suggest the 10% drop is more appropriate. IMO...YMMV and all that.

ah okay I get it now, but since I haven't strung up with synthetic gut in ageeeeesss i'll string the same tension I'm stringing my polys at now (56-58lbs).

When I'm in Hong Kong I tend to string 58-59 because I believe it drops a lot more at a faster rate(because of the heat), so this way I'd still be comfortable with it dropping to 56, for example. When I'm in sweden though, i'll string around 56-58 because up north it stays around 16-24 centigrade and is relatively dry so I think that the dry and cool climate has less impact on the strings.

Just really bad at following instructions and maths

Basicly if you normally get it strung at 60 you would get the polly at 54

and just in case you are wondering what will happen if you don't drop the tension, its like hitting at roughly 60 pounds when let's say you normally string at 54 and since its stiffer, you might have arm problems.

Do that. The 10% less advice is typically for those who are trying a poly for the first time. Since you are already using poly at 56-58, then even the polys that say "10% less" you can disregard. With the latest surge in poly popularity, many manufacturers now omit that recommendation since poly is not as new and unknown as it may have been (in general).

This will also help you compare various string brands, use the same tension.

At least you learned how to calculate % now

No reduction in poly cross tension??

Speaking of hybrids:

I initially strung polys 10% lower (particularly if poly mains**), but since a poly loses tension faster than syn gut or nat gut, I now string them at the same tensions (poly in main or cross).

Anyone else do the same? I don't feel a significant difference.

**Another view is if a poly is used in the mains, the crosses (syn gut or nat gut) will result in tightening up the mains. So, string the main poly at 10% less than the cross in order to equalize the stringbed. Other views?

Y = (X - X/10)
Where Y is Tension you string.
X is the recommended or your regular tension you play with.

I use a hybrid setup and I string the same tension. I've tried differing tensions when I first started and just didn't like it for whatever reason. Since switching to poly from Kevlar I've found that I like my old setup just the same. I've also kept the same tension.
