Saddly many bike shop owners don't know or care about what you want. They have no knowledege of creating higher performance only to replace parts with oem replacements. Sorry about your bad experience, not all are bad or self righteous some are actually pretty sharp. Your welcome to call my shop any time for quick answers.

I have no faith in human perfectability. I think that human exertion will have no appreciable effect upon humanity. Man is now only more active - not more happy - nor more wise, than he was 6000 years ago. Edgar Allan Poe
