I'm with the 'low' crowd
My method was to get the seat where I wanted it, then played with the mirrors and wheel till I could see everything.
There is so much adjustment available that it took some time to find the sweet spot, but I found it
PS - 5 foot 9 (on a good day
)
PPS - low just cos that's how I like it - gives a more sporty feel, and feels faster too
