I think you need an instructor sign-off for tailwheel in your log-book. This might not be done in your Rans.
It would be a very high risk activity to fly your early hours in the Rans without someone capable of sorting out a pilot-induced-oscilation on the runway.
Grass is far easier than hard surface. Don't do your first hard surface landing solo.
Take-off should be no problem. Landing is likely to be no problem - until after your gentle touch-down, on the centre line, in nil wind, and you relax
Keep looking at the end of the runway, and immediately you correct, counter correct. And be very wary of any tailwind component..
