Why would top players share much info? To make us better? They don't owe that to anyone. Making the beginners better only ruins their future competition anyway.
Look at online poker. All the free education took a lot of the "edge" out of the game for the better players.
I wouldn't even waste my time asking better players for tips if they are strangers. Build a relationship with some of them. Earn some credibility first and join a country club where they will perhaps befriend you and help you.
Put the time into the game. You don't get something for nothing.
