In a setting in which one is trying to compliment his band members with the sound of his instrument, dominance is an issue. I suppose the situation would differ if all members of the band used higher output pickups.
In addition the predictability factor comes from the view that the 81/85 combo is used in too many instruments and sounds similar in all of them, regardless of what materials are used in the instrument.
On another note, Vader is not a big name for bass enclosures like it is for those of guitars. If you're going to demonstrate name-preference for bass, the common brands to do so with are Ampeg, Eden, Epifani, and Aguilar. Please do some research before demonstrating brand-name pretention.
I got a response from another forum that was very experience-oriented. This happens to be what I was looking to find:
"I own the 4x10 model.
Compared to other aluminum coned cabinets, you still get all of the treble without the harshness associated with hartke and behringer, and other aluminum cones for that matter. (This is due to the treatment of the aluminum i believe).
And, even then you can still get a nice punchy and beefy bass tone out of this cab with limited treble. (It also works quite well with a lot of mids and some added treble, which is my main tone)
I play everything from techdeath, prog rock, and thrash etc., and for the price this cab beats most of the competition. The only downside is that there is no tweeter, though that can be easily replaced with good skills with an eq ;] And do not buy the backline series of heads with this unless your are going to run a sansamp through your chain; they sound weak without one. You are much better off with a higher end GK head or even an Ampeg (GK handles treble better though).
I highly recommend the 4x10 and 2x10 models, just try them out with your rig before you buy one though, it seems GK always puts out a few fluke cabs that like to make a LOT of noise when the treble is turned up; mine is fine, however."
I can form my own elitist opinions, but I try to stay open-minded and hear the views of players who have had experience with a given product. Personally, I've heard more good than bad about Gallien-Krueger. Isn't that the purpose of this thread? Why nix the idea of buying something you've never played?
