I play 6max so I'll usually call with Ax suited I'll usually call a 4xBB raise from any position regardless of how many people are seeing the flop. I guess this can be a leak, but I have a 10+ PTBB over 20k hands, so I'm not worried about it.

If you are talking about full ring, I would usually call a 4x BB raise from any position as long as 3 or more people are seeing the flop. Again I don't play full ring, so keep that in mind when taking my advice.
