parks is a faster board. i say the byerly is a much looser board, but then again I have the finless byerly. byerly is a smoother ride. both boards pop really well.
as for bindings, make sure to check out CWB zeus. similar in function to the belmont, but a lot lighter and more flexible. they hold you to the board really well, and the footpad has two layers, one squishy layer like the HL bindings but a little less squishy layer on top of that. this lets the landings be soft, yet you have a better feel for the board.
