Distortion of the racket when stringing crosses more than 1 lbs lower than mains
I have a dropweight stringing machine. If I string my crosses more than 1 lbs lower than my mains, I get a huge distortion in my frame (about 1,5 inches wider). This applies to all frames I string, and I have strung a lot of them. I had this distortion in the first two rackets I stung with the crosses more than 1 lbs lower, and I ended up cutting the strings out because it affected the playability of my racket.
Can anybody tell me why many people string their crosses 2 lbs or more lower? Is it just me who gets this distortion?
