Dont rely on canned material bud.
Personally dont think following this MM stuff that literally and used canned material like that.Though use some of the MMethods stuff in terms of situational openers which they teach about.
Anything about their appearance that you notice that you like,the venue itself,the band(good or bad).Make it up on the spot.Remember that an opener isnt everything.Some may disagree with me,but Ive personally seen tons of crappy ass openers with crazy results I mean take a look at Keys to the VIP,the guys there are pretty terrible most of em with openers yet they still manage to pull it off.Just remember to smile and possibly go out with a wing for mental support.
One last thing I might as well share that you could use as sort of "canned" material is something that I use frequently.Im big into psychology so I can kind of analyze people.I would do something like
Me:Haha fiesty
HB:What?
Me:Well I just took a glance at you and figured you seem like a fiesty girl.One that would snap in an instant and be ready to kick some ass I got a lil scared Im not gonna lie
HB:Haha ya I am actually sort of like that blah blah blah
^Ive used something very similar to this and gotten that reaction except ive modified it into an opener.Its money bud use it
Ive used it on like the harsh sluts and HB9's and its ideal because they usually say yes they are.Then you could get ones that say "Noooo Im never like that". BEST LINE RIGHT AFTER THAT is I get my sarcastic and goofy look and say "Be honest with me, I seem like the type of physically intimidating dude dont I?".Now Im not the biggest guy ever Im average size so this works out funny if you show your guns guaranteed a laugh
