I have that opinion because I've played tens of thousands of hands there, not because I've heard it a lot. The games are still profitable without bonuses, just not as much as the other major sites, so I have no reason to play there without a bonus.

I'm not sure what limits you play, but at 3/6 and 5/10 LH, the typical players numbers are about 12/5/1.5. I have a few regulars in my PT that have VPIPs less than 10 after over 3k hands. That qualifies as a rock in my book.
