Thanks LucieIsland, i appreciate you laying it on the table like that.
if i get the stringing machine i still have to spend 30min restringing them.
Pro pro's website is not great for explaining the difference between the strings in terms of durability. has cyberpower, eruption, blackout and concept the same durability if its the same gauge.
again, what is sustainability for you? ..
resistance to abrasion? .. to breack?
do you break your strings because they wear out from friction? or because it is off-center? ..
if it is wear and tear, I played for a while with fairly heavy strings, at 25-26kg, then I started to have a sore arm, and my brother made me pass very quickly, less from 15 days to 17-18kg, then I went from 1.30 to 1.20mm.
it's like a knife! if you press very hard (high voltage) you cut quickly, if you press weakly (low voltage) you cut less quickly.
people think that with low tension the balls will come out quickly, but in fact the stiffness and native elasticity of poly prevents that! Muguruza or Jack Socks are there to prove it, they have played (17.5kg for mugu) and still play for Socks well below 18kg! ..
with the power of some atp / wta players, when we see that some play or have played with tension as low as 20-21kg, we wonder how we could not play with these low tensions! if it comes out, it's a technical problem, no string!
then, you should know that if you really break with abrasion, you can climb very high at the level of the thick gauges.
but anyway, if you break strings in 2 days, upgrading to a higher gauge string doesn't guarantee you will keep your string for 10 days, and the point is not there.
remembering that somewhere you have a certain chance of breaking them, just as quickly, because the poly that do not break and stay sometimes 10 to 20h provide injuries and TE!
but currently, which gauge are you breaking? on real abrasion?
but of course, I would be you, I would use the thickest gauge, with a difference of 2kg for the crosses, and I would see what it was.
