I didn't get #10000 because I was advised against it by my sensei because of our hot summers. He told me a #8000 would be good enough and if I really wanted then i could get a #10000 set for seminars and exams. I'm happy that I followed his advise. Even though when a group got #10000 gi and hakama I was very much tempted to buy me a set too as it does look really nice.
