I just finished doing the swap myself, big time improvement on the ride.
I used a 4+ on the Clutch, and brake, and a 6+ for the throttle/Idle a tad long for the the throttle/Idle but had lots of roon behind the batwing to hide.
Went with the Cubby's WO575's armor braided cables, ISO grips, and the shilloette levers
I will try and post before and after pics tonight.
A BIG THANX TO ALL THAT LEFT ADVICE AND HOW TOO'S ON HERE.
You gave me the confident to try it on my own and saved me about $500 from the HD stealer I usually go to.
Thanx again

 

Finished with the install of the bars and retro radio kit.I had to reroute the throttle cables, that solved the binding throttle. I should of ordered a little longer throttle cables, like I did with the clutch, but my wallet was feeling a little light. The bars are much more comfortable for me, the bike feels totally different. The retro radio kit just plain ROCKS!! I ordered the Sony GT510, Ipod controller and JM speakers. Very, very happy with this set up. Night/day difference over my stock setup.JMO

 

I went with +2 braided cables when I put my WO575's on, No problems.
