I dunno Ken, I love you but my 8.5lb ash/maple DJ4 wasn't that great...might be personal preference...I didn't feel it had a great/good slap sound and the fingerstyle sound felt a little weak compared to the alder basses. We might have to agree to disagree...
That DJ with the Aero's is a very different sounding bass... very, very aggressive, and not a lot of low mids.... massive upper mid grind. It was even too much for me, although with the passive tone cranked back, it sounded pretty good. I agree on the slap thing... that model was all about the grindy, super upper mid bright rock tone.
I would think, for your tone goals, that bass would have been pure hell!
Edit: This brings up a good point though.... it all has to work together. For example, my ash/maple NYC Sadowsky with 60's pickup position is one of my favorite basses of all time, but with the stock HC pickups, it is a trebly, ganky mess up top (IMO) and too much deep low end versus growl. Stick some Sadowsky singles in there, based on one of the Seymour Duncan models, and it just sings. Those pickups have a grindy but not harsh midrange and some lower mids built in to balance wonderfully.... grindy but also growly, and plenty of top end for slapping on the rare occasions that is called for any more!
