I suppose it's a lot to do with the type and model of TD and the forward visibility each one gives in the landing config and also what the flap set up is will determine the need for slipping, my TD offers good forward visibility and has more flap setting ranges than you can shake a stick at, so my approach techniques are the same as how you would do it in any other trike spamcan, the differences start right before touchdown where in my plane I can not allow any crab or drift otherwise it's ground loop and chequebook time, where as in a trike you can pretty much land it arse for elbow and with the CG being in front of the mains it will just whip itself square.
