I agree, getting and taxi'n on the mains calls for a lot of "control" over
the airplane. I did this also, but didn't refer to at as "high speed taxi",
5000' on the mains requires a lot coordination. I guess we need a
defination of "high speed taxi" for the 701/750 so we'll all be on the same
page.

I fly from a 4200 foot runway. When I land I will keep the front wheel off the
ground all the way to the turn off at the other end. I have vg's which makes it
easier to do. With slats the on it is much more difficult to maintain the front
wheel off the ground, it either wants to go very nose high or drop the front
main to the ground.
I did high speed taxing with the slats on and can verify that it can be very dangerous.
You get up enough speed and the nose high and it will come off the ground.
The problem now is to get it back on the ground with out thumping it, cuz
when you come off the throttle it will come down like a rock. This is a real
problem especially when the end of the runway is approaching and boy does it
come up fast.
My recommendation is to take off and fly a few feet off the deck, if no bad things
seem to be in play then fly away. By that I mean no heavy forces on the stick,or
other trim problems evident. My trainer, an old military instructor told
me to never head right for the sky but to fly a few feet above the runway and
then if all feels right go up.
