Phenotype L imo is a great RDA. Stupid airflow but its there if ya need it I suppose. I close down all except the smallest and half the second smallest air holes and get great flavor. This attie is NOT for people who like regular ol coils, its made for big fancy builds end of story. With all that being said, I have 2 strands of ANNi80 fused with 38g LVNi80 dual coils in it and its crazy. That build gets such good flavor out of this attie. In general thats my favroite fancy build, its super flavorful. I have been really getting into building lately and I grabbed a 13 heavens 9 hells and IMO its the best deck on any RDA ever made IF you like fancy builds. Crazy deep, square posts and massive holes. The flavor off this bad lad is darn good to with a fancy build. I put 5 strands of LVNi80 ribbon framed with ANNi 26g and then fused with 38g Ni80 and it doesnt even take up a lot of the holes.
Im always a flavor guy first but I have really got into building and I find I can make just about any attie shine with the right build. The atties that can be hit with just a standard build and still shine with flavor are the REAL flavor atties, IMO of course.
