First time today stringing up a Prince TT Grande. i started with a set of TNT2 and after doing the mains i got the feeling i wont have enough string left. so i went ahead and measured the Xs. turns out i was right!!! i needed close to 2 lengths of X to finish the job. even with the 7-8inch slack from the mains i dont think i could make it. ended up having to use my own reel of string to do the job. never ran into this before. haha. i also had a tough time with the first X because i had to use 2 adapters at the Head to allow the mounting point to tighten the frame.
