I wouldn't advise playing with a different unfamiliar string for the first time at a tournament if I'm honest. What did you use before?
while i have done so myself, it is usually not a good idea to use a new type of equipment right before a tournament. on the other hand, it is OK to re-string your racket with familiar string & tension and re-grip the racket if they are showing signs of wear.
difficult to really recommend anything, if your happy with BG65 then I'd restring again for this tournament with BG65. Then change after the tournament to BG66U
BG66UM is thin string, and can break much easier than BG65. definitely recommend to stay with BG65 for tournament, unless you have more than 1 racket and still want to try the new string.
