I'm just replying at the end, but I wanted to add a few things.

I don't often vary my preflop bet sizes too much online, and mostly in position like carrotsnake was suggesting (raising pot unless in the blinds than slightly over pot usually).

I don't think its a leak to do so, even in a game with regulars who will pick up on your tendancies. What I mean is that I have a lot of tendancies that smart opponents can pick up on, and as long as you am aware of what they are, and can play other hands in that way or take a non-standard line for you, then I can use these tendancies to exploit them regular opponents.

Sometimes I think its worthwhile, if you think you are better than your regular opponents (who are thinking), to build patterns into your play that you know they will notice, and then switch things up.

When I play live I often use varied bet sizes to accomplish what I want to accomplish, I think the difference is one table, less hands, and better reads so you know which bet sizes will do exactly what you want to happen.
