Very interesting thread. I'm in a similar dilemma in terms of hairline design. From what I've seen on the forums, I would say Konior, Feriduni, Rahal and Erdogan are amongst my favourites in terms of a natural yet good looking hairline. As I am more leaning towards FUE, I think this is where there's a bit of a divide. Konior doesn't have many documented FUE cases (seems to be more of a strip guy). Feriduni had that one case (MBPsucks) that seemed to require a second session and I don't know what the end result was. I remember 2 Rahal FUE cases (Sean and Sugar) that seemed a bit questionable at some point but I think they have been sorted sine, unless I missed something. Which leaves us/me with Erdogan. I personally also like Bisanga's FUE work. His hairline designs might be less intricate, but he always seems to pull off great yield. Keser from Turkey was on my radar too at some point, but haven't heard much about him lately.
