When I'd get in an argument with my T over direction, I would decide to do it T's way because I was there seeing her and she had done "this" before whereas my way did not work for me anymore (which was why I was seeing her :-) In addition, if we did things her way, she could "help" and sort of lead because she knew the way but if we did it my way, she would be clueless and have to follow me and, you know what the bumper sticker says, "Don't follow me, I'm lost!"
Don't forget, too, if things down T's road aren't working? The two of you can decide to try your way; which way to go is not "all or nothing".
What's the worst that could happen doing things T's way? It might take longer, because it's not familiar to you and doesn't feel natural but most of that will be because you'll be learning something new! That's a good thing; having more choices of procedures in the future?
