I converted my first avistar to a tail dragger after about 4 flights. I think it's the only way to go if you're flying off grass. Like others have said keep the tail down with up elevator to retain control when taxiing . One thing a lot of people do on take offs is jam the throttle open and then jump into the air as quick as possible. Try opening your throttle gradually until you are moving forward than a little more until the tail comes up and let it lift off with as little up as possible.Jamming the trottle open increases the amount of torque and most have a tendancy to over correct. If this happens and you are able, stand behind the plane as you take off to see how much you have to correct. If the wind allows, try starting your take off from the side of the runway so that you have the whole witdth of the runway. Important thing to remember. As you begin moving forward on your takeoff you want to retain control by keeping some up elevator but remember that if you forget to bring the elevator to neutral the plane may lift off before it has sufficient airspeed.
one important advantage to tail draggers over nose gear is after a rough landing you may need to fix a bent landing gear strut or replace a prop etc but almost never fix or replace your firewall.
