I was stringing the crosses and when I got to the last hole for the tie-off knot, there was no room to slide the string through. It seems that the hole sizes are not the same throughout the racquet (especially at the 6th holes from the bottom of the racquet ). I noticed that when I bought the racquet, the strings were done with 2-knot method. I don't think the racquet allows you to tie 4-knots unless you want to tie the knot around the 9th or 10th hole from the bottom. I used an awl but it still didn't work as there's not enought room to slide a string through. I can't see any light through the hole unlike my Yonex racquet where I still see light through the hole when there's a string through it. I've never had this problem before with the Yonex's I've strung, so this must be something unique to the Sotxs. mg27
