It is slimmer than the XRA without a doubt. I have tried the Whiplash SPC, RSD Golden mk3 and the Truth replacement copper and the Truth is the only one that the connectors fit all the way in. The Whiplash also goes in all of the way it is only the RSD mk3 that doesn't. As far as the shell I requested Jack give me his pick so it is Jack's pick and I haven't had a chance to talk to him about it yet. The ridges come from the Final Audio tips.That looks good!, definitely slimmer than XRA. Is this Dean's new optimized shell? Btw, what tips are you using? I noticed some ridges outside of the core under the cap. And, with a cable, does the connector goes all the way in or you just have it in the picture half aways out?
