Narda kills the O-Atty in terms of flavor. Notice most people using o-attys are using clapton coils or even crazier coils. To me, what makes a good flavor atty is being able to drop in a simple single wire spaced coil and getting great flavor... and so far i haven't found anything better than the Narda. I also just picked up a Shift BF atty and so far i'm liking that as well, but it's a squonking only atty.
This became my mantra a long while back and pretty much stagnated me doing anything else. I'm pretty much never in here any more but the Recoil and Narda brought me sniffing around the past couple days. Crazy how much things keep moving. I went through I don't even know how many attys 2 and 3 years ago and just kept coming back to my Veritas and clone and it's (for the most part) all I've ever built since. Just plain-jane single round wire vert in a Veritas. Since I stopped monkeying around I've never wanted for more. It's kinda boring.
