So i know when you pre-stretch you get the advantages of getting rid of the coil memory, holds tension much better etc etc... But for some reason I totally forgot to tell my local stringer to pre-stretch my string But my question is even though my racquet is getting strung with a bg-65 with no pre-stretch(Ok he said there is a little pre-stretching but not really fully pre-stretched)wouldn't it lose the same tension as if it were pre-stretched? My stringer uses an electronic machine (8500 ELS i believe)
8500ELS is a good machine. I believe it comes with pre-stretch function, so your stringer probably use 10% pre-stretch. And for losing tension, BG65 is pretty bad, it does lose a lot of tension faster. You can try BG80 it gives better performance after all the pre-stretch. just my 2 cents
