Agreed, it will be a little unforgiving to work with but I'm fairly used to that. I had the house wired with solid conductor CAT5e (LSZH) and terminated most of that as 'flying' leads into the various bits of kit I have. Even the cabling into the master socket is solid conductor CAT5e. I've got used to the rigidity and just make sure I don't bend it through tight radius'.
I think the cable I'll make from this will only be around 25cm long and should be fairly straight. I can always use a heat gun to help curve it to shape too I guess. If it's too unforgiving, it was only £5 so I'll just scrap it and find some more flexible stuff elsewhere.
They did have some indoor spec cable but, it didn't explicitly state it was CAT5e and there was no labelling either so, I didn't want to risk that.
Useful information on the supplier so thanks for that.
I did also find some fancy German made 2 pair stuff but, it was shielded so that put me off. It did look nice though!
