Constantly having to Force Reload You Tube

Safari 6.0.2 in Lion - the title says it all - I can't navigate back and forther much at all without slowing/freezing and getting the SBBOD (spinning beach ball of death) - having to CANCEL (X) loading the page and then getting the Force Reload dialog.

It's happening to me constantly on You Tube. 4-6 pages or so and it's dead. The only extensions I'm using are 1Password, AdBlock and Ghostery. I've quit and restarted Safari - no help - RESET Safari is next, but this seems to be coming from You Tube themselves partially since there are no problems navigating to any other site.

Anyone else having these issues or know what's going on?
