If that's the case then "Abraxas" really is a bad name. To me that evokes the tone of Black Magic Woman, Samba Pa Ti, etc., not the mushy PRS sound.
As to necks, they're not super-super thin, but I like a bit more heft. I think it's somewhere similar to a Fender modern C neck. My SG3000 is 4kg, so the weight's not too bad, and my SG1300T is 3.5kg, not bad at all. The latter has a body that's maybe 1cm thinner. It's a bit like an ESP Eclipse to the SG3000's Les Paul.
