I have a R4JB from 2006. It is on the heavier side, probably about 9.5 pounds.
It has a nice, dark and even colored board but Beck's original had a light-colored streak on the bass side of his board and I have seen some of the limited editions attempt to duplicate that.
If you are looking for a lighter one... Keep an eye out for the 2013 Benchmark Collection Oxbloods. They tend to be in the 8 lb range. Mine is something like 8 lbs 5oz.
