Move to a tougher site?

[mjm]

I have been playing on-line for approx 1 year, with little previous hold 'em experience. I chose to play at Pacific Poker as a few people told me it had the 'easiest games' on-line.

I am now at the stage where I manage a small weekly profit from playing, however I am trying to improve my reading of hands based on opponents play and am concerned that Pacific is holding me back (it could of course be simply I am not yet good at it).

Many of the plays I find bizzare (in a weak rather than strong sense).

Have others found this about Pacific?

Is it worth playing at a stronger site where games are tougher but reading is more likely to be possible?

Is reading hands easier against tough players than weak players?(I assume tough players will make a lot of moves)
