I have a CHR based PDK EK 15/5 Paladin w/SWF that is similar to your build in that I picked up all the Cleaves I could as the EK DPS is just kind of meh + being a CHR build it will never get as much omph as a STR build, thanks to Divine Might - but it is fun - so win/win.
With a STR build S&B/THF I didn't see the point in picking up the Heroic Cleave Feats as the Cleaves in the KotC are better and share a cool down - do you think they are necessary on your build? Or are you just going for flavor? In any event, I like your build and I hope mine works as well as you reported.
I've done a test build of my build above with a PDK and ran it for a level through the big fights in DD and Storm Horns and it seems to perform well, even though it has just the starter gear (which isn't bad) and isn't exactly the same build - but close enough to get a feel and I didn't even notice not having evasion. In fact I'm second guessing the inclusion of Insightful Reflexes now... I might drop that and make room for Improved Shield Bash... or Extend?
