A couple of things just occurred to me... A nice thing about good pickups is that they don't lose value. You could, conceivably, try both pickups and see which you like best.
More practically, and sorry for forgetting to mention this before, but I just remembered. DiMarzio J's are slightly larger than standard J-bass pickups. You may want to make sure they'll fit...particularly the bridge pup before you sell the Toneriders, unless you've already checked ;-)
(They fit in my Frankenjazz...but I read on the website that this can be an issue).
