Flair has low GMP so not many members come here they are at Tata n Gandhar but I always prefer small GMP ipo because that is what I got most of the time small small profit will make big one
Gandhar will give around 9k profit n Flair might be 6 to 7k both are good company so you can hold for long if long term investors all sell on listing day capital on pre opening n remaining after that
You can take out capital on listing day or within short time and then kept remaining if you are investor else sell all and moving money from one to another ipo
