Ok, so you've got some life events. The move would be the biggest detractor for me so I get where you're coming from there. We may have only a fraction of the story, but you have three people who are very comfortable with electronics telling you its better to repair the existing infrastructure than run new stuff. Experience counts for something, whether you choose to believe this or not. Your example is not valid. If I'm doing a job for a customer, I would be doing it to their specs for colors/materials. As the craftsman contracted for the job, the method of execution is up to me. If the customer wants to try and tell me my methodology is wrong, they can pound sand, unless they themselves are considered a resource in the topic. If a master upholsterer told me I was doing it wrong, I would listen and ask for assistance. I equate your question to a rookie tech asking a master tech how to accomplish a task. You however continue to justify why your view is superior to the expert opinion you sought in the beginning without presenting anything more than "I don't want to do it that way" as rebuttal. For someone who has proclaimed them self to be competent in reading schematics and troubleshooting circuits, you are sure going out of your way to not even attempt this.
