Yeah, I've had the pickups out on my 98 and it's got a nice thick cap. I can't comment on the similarity of the neck to an R0 vs. a more modern Gibson slim taper though. I can say that the necks feel great.
it's slightly bigger than a slim taper 60s or R0 neck. nowhere near gibson 50's profiles, much closer to the 60s. i found it comfortable and i'm not a fan of the R8 or R7 necks personally. i hope that helps.
i was able to play Whoopy's recently and i hadn't played one up until then, i like them.
