I'd step up to either the Youngblood DoubleDog or Destroyer Chili. I think the Custom is just not better enough for the money and well you already DON'T have Burton bindings. Center to flat rocker in my opinion does no work well, so I'll suggest against the Banana. Chili and Arbor's system rocker are the only center reverses I've ridden without some sort of recamber that I did like. Others you may want to consider are the Flow Era or CAPiTA Green Maching FK. I have reviews of both in the review section.
Go ahead, drink that kool-aid.
