Hi simon, well done!

In my opinion, mains are done 2lbs less than crosses.

With regard to finishing the main strings (I assume you are using flying clamps, not fixed clamps) when you tension the string where you have missed one (so the second to last main string that you will tension), I find I have to clamp (with flying clamps) in the middle of this string, against the string “next” to it. This makes it sag and look strange, but thats all you can do. I think even with fixed clamps, it is difficult to clamp it anywhere other than the middle (depending on the machine).

So when you tension the FINAL main string, get a little bit of tension on it, but the flying clamp is in the way of where the string wants to go. Before you pull at full tension, consider carefully removing the clamp, and then finishing off the tension. You then clamp this FINAL string (which is the second one fromt he edge) against the one further in (the third one from the edge) because this allows you to clamp closer to the end of the string you just pulled, and hence retain a bit more tension.

Grommets are slightly strange in my opinion. If a grommet is broken, such that the string would rub against the racket frame, then they need replacing. You simply cut them out or try to use a degrommeting tool. I may need to be corrected here, but Yonex have their own grommets, and you won't in theory, get the best out of your racket unles you use the yonex grommets. Every other manufacturer uses fairly standard grommets, labelledd B2,B3… B6, which are simply different thicknesses and different lengths. If you are using these (on non yonex rackets presumably) the grommet that fits snuggest into a hole is the correct one – it shouldn't be loose, but you shouldn't need to use a hammer to get it in there.

I think that was everything?
