Playing the guys you can't beat makes you a sucker and likely they won't really want to help their good old cash cow progress...
You don't need their "help"; you need their competition. My opinion only, of course.
Getting a spot from the guys you can't beat will earn you more respect than being a sucker and as long as you are always willing and clear about constant adjusting they will likely share some wisdom since they know if you get a little better the spot will adjust and who knows maybe you will bet higher.....
I never minded being the "sucker" for a while, since I knew it was in the name of learning and improving. Those guys who I used to donate to don't think of me as a sucker any more. Some of them merely respect me, and some of them fear me. Again, my opinion only, but asking for a spot to avoid being the sucker seems to me like it wouldn't have forced me to improve as much or as quickly.
I guess it's clear by now that mileage varies from person to person, and surely from poolhall to poolhall as well.
