i always had trouble with curly leads, especially on stage work.
as you dont stay in one place the connectors in the jacks tend to get pulled and twisted as you move around, eventually coming loose, crackling etc.
if your just sitting in your front room jamming away you should have no problems. if it's stage work, make sure you carry a spare.
i love fenders myself and have a strat and tele (mexicans) though i find the quality excellent, i do find they make a bit of noise whereas korean or japanese guitars are quieter. i've never recieved a lead (curly or otherwise) with a new guitar. maybe they take them out in the UK!
i used to make electric wire, and i can tell you the best wire to get (if your making your own) is computer cable. (it needs to be shielded though) the noise you get comes from the fact that the copper is rough. smoother copper creates less resistance so less noise and the sound will flow easier.
hope this helps
