1. There is no threshold . I have had super hot girls agreed to come straight over and have had average girls balk at the idea. A girl's attractiveness is not a factor here.
2. No, some girls will not meet you straight at your place purely out of safety concerns. I have had great experiences with a good amount of girls who didn't come straight over.
3. There are details guides (including one in the product) on this and it will take too long to properly explain here. And, no, it is not always your fault.
4. It really depends on a girl . Some chicks are totally cool with having a friends with benefits relationship indefinitely. And some girls will catch feelings very quickly and want something more. Most girls are going to be somewhere in the middle.

or something like: "I can invite you, but need to know something first"

1. yes, it is possible to do everything you said correctly. However, unless , you have really solid game , you are much more likely to fuck it up and have a girl think you are creepy or weird. My advice, is to avoid unnecessary complexity and just keep things as simple as humanly possible.
2. " Oh, I doubt that ;)"
3. "Don't worry, you are the only one that matters" and " Only the ones that matter"
4. "Wine and massage oil", "Do you enjoy multiple screaming orgasms"

Don't be afraid ever to go for what you want. People will not judge you, they will respect you instead.

My personal approach is to try to bang every chick on the first date so I can relate. There are series of thing you can do to screen better. If you are in a good shape, get a solid shirtless pic and put it in your profile that will screen quite a bit. You can also screen harder in the bio. Furthermore, there are a series of ways you can screen in your messaging.
You can go direct "what are you looking for on here"
Or a bit more indirect as is my style nowadays "we should split a bottle of wine on my romantic patio "

Also, whats your take on adding chicks off tinder (or in general) on instagram? I know JMULV isn't a big fan. But let's say you ask her if she's got more pics of her and she then replies 'yea add my insta'.

I like to keeps things as simple as humanly possible . if the goal is the same night lay, than there is nothing better than inviting the chick straight over. If she says she would prefer to meet in public first, than Starbucks or something simple like that is your best bet. the more complexity you add to the situation (ie. unique date) the less likely you are likely to achieve your goal. Save the cool dates for after you bang.

If the girl messages you first that generally a very good sign. I would more or less match her vibe "Hey what's up" and smoothly move things towards a flirty direction. And yes, I would always try to go for the straight to the house wine date first. Even if she objects, her response will give you a good idea whether she is worth meeting up with. For instance, if she completely balks at the idea than she might be a waste of time. however, if she says something like " Is it ok if we meet for a drink first " than you should do the public date.

My strategy with Hinge is to like pics. I will either like the pic that catches my eye or like her strangest pic just to see how she reacts. I will wait for a match before messaging the girl as the odds of her responding are higher. However, I don't think there is anything wrong with messaging the girl before you guys matched either.
It is important not to overthink the frivolous details and focus on what really makes the difference... Having the best profile possible, solid text game, and running high volume

Thanks man, I appreciate it :)

1. I would just be honest about your career. Say something along the lines of "I am a male stripper. And you?" . Then, keep that joke going for a minute or two before ultimately saying "Alright, you got me. I work in finance".
2. That's a bit of oxymoron. There is no way to stand out with generic comments . Sometimes, one a girl is giving me a little sass. , I will say "So sassy" , you can try that. But, to be truly unique the comment has to be situation specific.
