What do you mean by "axle carriers"?
I think they did a great job on DS9...I guess it's for the pros as it is for the rest of us - the best job possible is done with available references, and then a new reference shows up! If/when I ever do a good K-7 build (I have the AMT kit already), I'd have to try to follow their work, simply because the on-screen presence of their details is so much greater.
