On a more serious note, with sticky cables your shifting will always be an issue. It is more likely the cable running under your bar tape, than the short back section at the derailleur. IMHO any type of lube will make things worse longer term. A high quality cable set, will set you back around $30, making the upgrade worth your while.
Very funny!

I haven't ridden much in years, and I'm 52. It takes me three days to recover from a 10 mile ride! The cables on this bike are routed internally, and that is probably part of the problem. I'm going to check the cable in question for obvious problems, and maybe try some graphite. It that doesn't work, I'm going to have to buy some type of low friction cable. Having to fight a shifting problem is not acceptable to me.
