Sounds like you are on the right path and glad to hear it.
Let's add: Make an effort to target the less stable offerings (team totals, props, second level sports etc).
Arena football, CFL, Golf, UFC, NBA Summer League - sports like that.
You'll generally find weaker starting lines and more variance in what's available due to a lot of
it not being on any lines screen. For someone trying to build a BR these provide stronger edges.
The limits won't be all that high but for bankroll-building players that shouldn't be an annoyance just yet.
