I have a PRS double cut away clone and it is ebony neckthru, 27 fret 7 string with a 28" scale with a African mahogany back with a 3/16 quilted maple top and it is lighter than the gibson. My gibson weighs in over 13lbs. Mine is not chambered. Not to be negative, but I always hear everyone saying, " oh my good a solid ebony neck is really heavy thats crazy", I have not had any problems that is a preference, I also prefer baseball bat necks as well. I have big hands and I hate a skinny neck, I think it boils down to preference. It may weigh close to the my gibson or slightly more, but it is not that big of a deal really. i know people that prefer Ibanez style wizard neck profiels and they think my guitars are heavy or have "thick neck's", I think it is perfect, I also prefer high action. FWIW it may be heavy but it's not a big deal, it's not going to weigh 20lbs or anything at most 14-14.5, with the case of the Dc PRS clone, the weight is a few lbs off from my Les Paul, I think it weighs like 11.7, basically 12, and the Les Paul weighs more
