Ring Game Question and help

Hey guys
This is Zack here.Needed some answers or close to answers about some ring game weridness going on.First off I have been playing .05 /.10 NL on full tilt after I deposit for the first time since two years ago when I was just learing the game.I seem to be doing good at the .05/.10 NL cash game ring I play 9 handed.However on pokerstars I'm running bad on .01/.02 I play on a 6 max and full ring as well.It seems wierd that I'm doing better at a higher limit on full tilt then the limits at pokerstars.Is it the players that I'm playing tougher at the other site? Or is the limits on Pokerstars to low that it warrants people that chase and call with anything?I play the same way I play at full tilt.Please help a brother out!!!
