My advice is to read everything in
this thread. Then post hands on the bubble that you are unsure of. This forum will tell you what the best play usually is.
What buyin are you looking for advice with? The 11s play a lot differently than the 109s. If you're playing 11s-33s, I hope your "rock solid" early play means that you fold a lot during the early rounds. That is what you should be doing. When it comes to the bubble, the blinds will often be large enough that you will either be pushing or folding preflop. There are some brilliant threads in my link above about bubble play.
