Mine is mahogany/myrtle and weighs the same. You can generalize somewhat about weight, but I think it's really dependent on the specific pieces of wood used because there's so much variation.My lightest 535 was probably around 9.2 pounds (I specifically requested light ash)
If you're doing a custom build, and you have a weight range and wood combo in mind, you can probably achieve that as long as you're up front about your goals. (i.e. don't leave it to chance based upon wood types alone; let them know where you want this to end up weight-wise.)
