Starting the crosses??
 

I went on the Wilson website and looked at the stringing instructions for tennis racquets..

http://www.wilson.com/en-us/tennis/s...-instructions/

and

For all the racquets that have their mains ending at the bottom, the instruction say to start the crosses at the bottom. BUT how come people on this forum say its bad to start the crosses at the bottom?? Should I listen to Wilson or listen to you people on this forum and use a ATW method instead? The wilson instructions say to start the crosses at the top for only the racquets where the mains end at the top, and there is only like one or two racquets that do.

I have a 6 point mounting system on gamma progression ST - II , wouldn't that help stabilize the frame?

1st off, don't treat as gospel everything you read here. If the manufacturer allows bottom up stringing, then they think it's ok to do so without damaging the racquet. If you think that is likely to damage a racquet, then by all means do your crosses top down. Just be aware that you are deviating from maufacturer instructions.

You could always call the USRSA (United States Racquet Stringers Assoc). As you have found out, some manufacturers (Wilson, Babolat) allow you to string from bottom to top. Yes, they are usually strong enough, and even if they aren't, Wilson and Babolat will replace them if they are still under warranty. But, you'll also notice that if you string the same racket 2-piece, they recommend starting the crosses at the top. Wouldn't you think that if it was the best practice to string from the bottom, that they would tell you to start at the bottom even when doing a 2-piece? I guess until you've seen a racket break from stringing it from bottom to top, you probably won't be convinced. Best practice is to start your crosses at the top.

Head is probably the biggest reason we string Top to Bottom or use an ATW pattern. By default, two piece jobs are strung Top to Bottom. Personally, I dislike ATW patterns, I'd rather do a Two Piece instead. One Piece is just a convenience, and if allowed I will do it even if it means stringing from bottom to top.

FWIW, even if one were to string from bottom to to in a Two Piece, no one could tell the difference. You will also find that the other racket sports, bottom to top is a common method.

Almost any Wilson can be strung 2pc top to bottom.
The last X tie off varies considerably.
Just find the big grommet, even if it's 12T or 13T.

Go with what the manufacturer calls for, not what some hacks on a website tell you.

Almost all Wilson racquets, with a few exceptions, allow for either 1pc or 2pc stringing.
USRSA recommends that when given the choice, use the method that weaves the crosses top to bottom.
You didn't mention which racquet you were stringing.
There are some(e.g. nFocus) that require 1pc only, bottom-up (or ATW).

I think it also depends on how you string the racket. Many people like to string one or two crosses with the short side. If the long is routed to the grommet closest to the outside main grommet hole I do think it is a good method.
