Yes Buonosera, using a RDA seriously bring out the taste and favour of the juice. I tried the same juice on a tank and dripper. It is total different.
Like others seniors here had adviced me before. Start with a single core dripper and get a VV/VW for a start. As single coil is easier to do and also to avoid sub-ohms caused by dual coils. VV/VW is better as it can set the voltage or walts as this will also avoid damaging your batt n mod. Some can even read what ohms you build for the coil.
As for model.. i started with igo-W(dual coil- 6USD) but only used one side. and Tesla vv/vw mod. Try
