My guess is that you really want to hit the 1.80m mark (night height). And my advice is to not chase a number. When you are walking in the streets or going to a club or doing any other social activity you won't have a number above your head showing your height. It's just a number and no one will give a fk about it but you. So, if you really want to do LL, go for it and stop somewhere where you feel comfortable with both your proportions and height.
