point 1 - you are a absolutely right
point 2 - you are right V's can be setup to be just as powerful. There are points for both. The fade quicker but are lighter. The pads wear quicker on v's but the pads cost way more on discs. Kind of a personal thing based on the type of riding you do and how wet/muddy it will be
point 3 - damn straight
No reason you can't do it that way.
