Welcome to the site i prefer grinding cash games to small tournies/sng's and 100 is enough for 2nl or 4nl/5nl.Id also choose a site with more fish than regs and a better bonus deal.Pokerstars just doesn't offer anything to players anymore especially players who want to play a good amount of volume each month.
If you go through a good and trusted affiliate like RakeTheRake you can still get 55%-75% rakeback on ipoker with
betfair and it's the old rake contributed method still on there.Which works as 35% flat rakeback 10% bankjob promotion 10% rakerace 10% reward tickets and 10% from other bonuses they run each month.So still a fantastic deal to have and helps build that bankroll faster.
Gl to you however you choose to build that Br.
