I'm not a pro player, since I'm quite new into the game. But I've been clubing a hell lot all over Europe, so what I can share is what worked with me in very loud clubs:
- Eye contact: Try to make eye contact with a target. When a girl look at you, look back at her, don't avoid her eyes. If you can lock in a girl's eyes, that's already 1 IOI.
After that, you can try whatever technique from the smooth approach to the "come here" technique.
- The dancer: Well, this one obviously needs good dancing skills. By showing great dancing skills, it's a sort of DHV. Many times I've been picking up girls without talking at all, just by dancing. But again, you'd better know what you're doing. And I think it's pretty worth the time & money to learn how to move your ass decently on the dancefloor.
- The bar: When you spot a target on the dancefloor, you can just wait for her to go to the bar, and go to it right after her. Then try to get spot right next to her and act like you're about to order a drink (or actually do it ^^). While waiting (cuz in clubs you usually wait a hell lot for the bar tender), try any opener with the target. It may work in some clubs, as normally, the bar isn't right in the dancefloor, so it may be a little less loudy.
ok these were my 2cts for now ^^
Hope you'll get some other tips to put into practice, and let us know how it goes
