Have a look at Erics, they are doing a half price sale on terminal stuff, it will cost you £5, p and p, order on Wed pm and it turned up on Friday, so good service as well
With the KD I use either a wide gape or kurv
IQ soft is good if you are fishing clear water, but is difficult to tie until you get used to it, don't be fooled by the name it is quite a stiff material good for stiff links or chod rigs
People say that you should use a lesser bs hooklink than your mainline, but it is difficult to find 12lb bs material, in the main it will be 15lb or above, as long as you don't go higher than you mainline you should be okay
