Those numbers are on the small side but there are some things to consider:
1. east coast: small hills mostly park. This means you pretty much don't need any size for anything (size adds stability at speed, among other things)
2. there is no RULE, but those are pretty small boards. I ride blunted 154 NS's and I weigh 180. I would say I'm pushing the size limit on those boards, but that's just me.
3. if you are sticking at 220 I wouldn't go smaller than the '53, that is still VERY small for your size. The only reason you like the smaller boards is because you are new and they allow you to ride them with terrible form because they are so easy to manipulate. At the same time for park the size is not that outta whack. If you didn't already buy it I'd aim you at a 56-58.
