I have precisely 1 hour in a 170 so here's the sum total of my taildragger experience.
After about 2 takeoffs I was able to perform the takeoff totally unassisted, yes it feels odd to push the stick forward to lift the tail but that's really the only thing that felt new to me, the rest seemed quite natural to this fairly low hour nosewheel pilot.
Landings, well after an hour of circuits I was able to three point it on the runway but then my instructor had to take over each time. Why? My lazy feet. The 170 especially likes to ground loop (even my instructor admitted it would get away even from him from time to time). I think the tap dancing analogy is apt. Be prepared to use your feet, and its the opposite to your takeoff, as you slow down you need to put in more rudder to make corrections and it was this progressive requirement that defeated me.
Good luck!
