go for the Axiom Streamliner or Streamliner DLX with p clamps.Instead of panniers that sit low and will require them to sit too far backto prevent heel strike get two 13liter dry bags and strap them off at the the sides and top rail with another bag tied to your saddle and the top of the rack. This will enable you to keep the weight as close to you. Then configure a compression stuff bag tied to the handlebars. Rely on pockets and top of back rack bag for frequently needed items. The streamliner with it's third strut will keep the dry bags from falling into the wheel. If you work with webbing, fastek buckles and bungie you can have a solid setup that won't flop around but you have to be vigilant to not let any loose straps fly into the wheels. Panniers aren't the only way to carry stuff.
