You are 100% correct. the cover is the main focus of how the ball will react. i always start with oob - then i adjust it from there. i have a Defiant that just didn't finish as strong as i wanted too. so after making some cover adjustments the ball is working how i want it too. take big jakes advice, if you have a ball that just is not doing what you want, going to long, breaking too much, etc. adjust the cover! you just might have the ball that you've always wanted, but you already have it. you just didn't give it the correct surface.
