wish i have taken a picture, my newly strung at900 BG85 @ 24 broke during first use, and then another at700 BG65 @ 25 broke after a week, i think something is wrong here. usually i don't break strings that fast, but then again, i never strung tension this high before (i used 22/20 for a long time). both racket strings snapped at top corner near the A8-12 grommets, maybe i failed to tie off properly? after clamping last strings i do not use awls to station grommets, could this be the problem? thanks for any help.
