That's about where you are inspecting 11 kv power lines a lot of the time, and as lifting says, you don't want to be there in anything that doesn't have a high-inertia rotor.
So, assuming a 206, you wouldn't want to be doing anything with the cyclic, aside from a small correction for the nose down tendency (the 500 seems to do this more than other machines) - you certainly wouldn't try to slow down either, just accept what speed you have. Otherwise, dump the collective straight away, keep the attitude and at the right moment HEAVE UP ON THE COLLECTIVE progressively and smoothly, co-ordinating the pedals, keeping the fuselage and skids flat, as mentioned. The 206 for a very short time will produce more than it should in such a situation (see Dennis Venturi's article in Helicopters magazine - a Canadian one - many moons ago), and it works best in a vertical auto.
It is important to use all the collective you have available in a rapid, smooth movement. As fun police says - bend the pole at the top and at the bottom!

PS - this is an advanced technique and not to be tried while solo or by the inexperienced!
