How successful have people been in negotiating a better split? Any tips to get it more in your favor? Opinions on what is possible?

I have really been wanting to take the plunge locally (for fun) as there are very few locations worth visiting in town. I have a nice establishment less then a mile from my house and they have a regular hipish corporate 20-35 working crowd most days but are not much of a foot traffic location.

They have no pins but do have darts and pool from a local operator that has given the OK for pinball to go there since they do not care to operate pins (they have a few but do not maintain them). The bar/restaurant owner really wants pins.

My thoughts are that time would be best spent putting 4 pins in this one location (also makes per game city fees less and is goes down on a per game basis) as 4 pins could bring in players and I could also do a monthly league at the bar to help bring in people and generate some excitement. My feeling is that 2 pins are not worth driving to but 4 nice pins are worth the effort to many players?

thoughts?
