I would simply recommend going for the tandy cable, least hassle, best performer, as one can't make them up with the nice moulded plug boots.
Burakkucat has rightly pointed out in earlier discussions elsewhere that these screened/shielded cables should have an external ground connection for the shield. The Tandy (former adslnation) website even mutters vaguely about the matter.
I notice that the A&A shop even points out that those straight-through plates have RJ-45 sockets on them, so I understand why CrazyTeeka might wish for the most snug fit possible, although I have to admit I never even noticed that my own A&A plates are not using RJ-11.
Perhaps you can't have quite everything. But there are manufactured products that are way more than good enough for ADSL/VDSL.
That's just my personal take on the (rather off-topic, mea culpa) modem cable saga.
