I wouldn't consider myself a loner, I can roll 5 deep or by myself to a club and still get numbers. However its been my experience that 1 night closes(straight from the bar/club to my place) are significantly easier solo. This usually works on a group of two girls, but the key is to projected confidence and indifference to their attention. Also arrive at the club early then you would if you were with your boys.
