What you are doing is correct :) I rarely land rear wheel first, unless I make a mistake. It almost feels like I am landing with both tires at the same time, but the front does come down just a wee bit earlier. Landing with the rear first usually smacks the front down unless you get on the gas quickly. ?I prefer the front to come down just a split second before the rear. if you find your landings a bit harsh, get on the gas as soon as you land, it will take some of the harshness out of it..
Good Luck!! :)
