i agree with you sam but i dont ahve problems with tangling unless i do something stupid, but i do use anti tangle stuff on my rigs anyway so maybe thats why.
also you dont need to use a different amterial for your rigs, when i first started carp fisahing i was using a yellow 15lb mainline for my rigs and it worked fine banking me a 26lb mirror, mono has proberly cuaght half of my carp.
Also when it comes down to choosing your hooklink its more down to personal preferance than what other people say, by all means use the infomation we give you on the forum but remember its about what will suit your style of fishiing.
