For reasons I don't want to go in to, I'm not going with clipless pedals yet. But on my next bike I want to make sure everything else is setup to the best possible configuration to prevent both upper back pain, and knee problems. Since clipless seems to be a big part of a fitting, would something like a BG Fit or Retul be a wasted effort? Will all the fancy ergonomics still apply if I'm using platform pedals and clips?

Some thoughts would be appreciated.
