Flux are what I would suggest. Either this years Titan RK or Titans. If you do not mind cost then go for the Distortions. The caps change a bit for next years models so they become convertible, so you will be able to be used either way. Next seasons SR15 will be a nice freestyle binding so would look into them if you can wait on them.
Some nice upgrades to the bindings over all will be coming out for the 2011 season.
