What does this mean, how is it done and what are the pros and cons of doing this? I've been having really bad stringjobs lately, they just feel bad and they suck, they even make me play terrible because I just don't have confidence and the ball can go either very well or very bad just like that. The feeling I get is that the string bed feels "uneven" or "unbalanced", like maybe some strings have a higher/lower tension than others and vice versa, it doesn't feel "compact" then, I don't even know how to explain it, it just doesn't feel right. Right now I'm only using 1 kind of string on the whole bed, Enduro Pro 16 or something similar. When I use only 1 string, should you string both mains and crosses at the same tension? Should stringing the crosses lower be done only when you use 2 strings? Someone who used to hit with me who strings his own rackets says that the difference is that he "double pulls" all the strings when he's stringing, he says that that makes it hold the tension evenly or better or something like that.
