Full Tilt 100% cashback

[X-Man]

Has anyone done this one or can recommend anymore.Full Tilt looks good but the snag I can see is the times I can play there are not many players on the site,which throw my calculations out.....Play $1-2 limit 5 tabling will take about 40 hrs to get the full $600 back,this is based on playing very tight and not being involved in many pots...Any better ideas would be welcome/does anyone play this site/what are the peak times???

Thanks
