To be honest CDM, it sounds like you've made a pretty good start right there! Don't worry too much about nightclubs being good or bad or whatever else, if you spend long enough practising there you'll work out the angles.

I've had many discussions with my wings about the dynamics of different places. In Liverpool, for example, you need to take a subtly different approach to pick-up if you're upstairs in Hannah's bar - which is quite chilled out and relaxed - than if you're in Bumper - which is more upbeat and energetic. This should seem obvious, but I find its a point often overlooked.

As ever with this stuff, there are very few rigid rules applicable across the board. There are subtleties to every aspect of PUA. But you seem to have grasped this already

All in all though mate, I'd be very encouraged from your experience last night. As a starting point, that's really positive.
