Right after my achilles tendon healed, my rear derailleur stop failed. (Similar injury, lol.)
I ran full cable from the front cable stop to the derailleur under the bottom bracket, and all was well.
Found a cable stop that matched.
LBS was WONDERFUL, bought the bike from them, and they sent out the frame for repair with the matched cable stop to a specialist.
The repair lasted a couple of months before it too failed. (The stress of a cable stop is much higher than many people imagine.)
In hindsight, I wished I'd just stopped at running cable under the bottom bracket.
So, don't let pretty be the enemy of a good honest repair is my advice.
