This might be a dumb question, I have been looking for an explanation but unsuccessfully... In the past, when using the wooden and aluminum rackets, the practice to stringing the crosses in badminton rackets was Top Down. Stringing the crosses starting from the bottom would change the racket head form and was an absolute NO NO. What is the reason now to do the crosses starting from the bottom? My stringing machine is an old 30 years from Fleet (now Felet I think) and I string only mine and my wife's rackets, and occasionally for a friend - I do the crosses bottom to top now, as seen in the instructional videos in Youtube. But I still like to do a good job on the rackets even though is just for my own rackets! Thank you, and apologies if this is a dumb question.
