I tend to start the flare at 40 feet.
The boogie is a bit tricky, but letting the stick go back to its neutral position after the aft main wheels touch down gives a reasonable derotation. Pulling the stick then slightly back for a second time helps to get the 2nd pair on ground, without raising the nose again, and finally you'll have to land the nosewheel aswell.
Conditions permitting I try not to open the reversers until all main wheel are on ground.
If you're coming from the A320 family, you'll have to get used to make a more positive input during the flare, or you'll hit the deck.
Also the fully configured attitude is a bit more nose up than its smaller counterparts, hence you tend down to lower the nose.
